When You Do Not Like Their Friends
Sources last read 2026-07-29.
The short answer
Banning the friendship is the one move that reliably backfires, because it moves the friendship out of your sight rather than out of your teenager's life, and it costs you the information you were relying on. Change the conditions instead: where they spend time, who else is around, what time they come home, and how easy your house is to be in. It is also worth knowing that the influence you think you are watching is usually smaller than it looks, because teenagers pick friends who already resemble them.
Why a ban is the wrong tool
It is the most reliably counterproductive move available to a parent, and it fails in a specific way that is worth understanding.
A ban does not end the friendship. School is six hours a day and phones are the rest of it. What a ban ends is your view of the friendship. From the moment you issue it, everything about that friend reaches you late, edited, or not at all, and your teenager has learned that telling you things carries a risk.
It also changes what the friendship means. A friendship you have forbidden becomes evidence of independence, which is exactly the currency that matters at this age. You can raise its value without touching its content.
And there is a cost you may not have priced. If the ban works, your teenager may end up with less than they had. A teenager with a friendship you dislike is often not choosing between that friendship and a better one.
That matters more than it sounds. A 2024 review in Frontiers in Developmental Psychology pooled 31 publications and 14 long-running studies covering 19,806 adults. Withdrawal in childhood and the teenage years predicted adult social anxiety fairly well. Its links to depression and other anxiety disorders were weak. The studies varied a great deal, so this is a tendency and not a rule. The plain reading is that the strongest thing withdrawal predicts is more withdrawal.
The reason the influence looks bigger than it is
Parents watch their teenager's behaviour drift toward a friend's and read it as influence flowing one way. Researchers have the same problem and have a name for it. Selection.
Teenagers are not assigned their friends. They pick people who already resemble them, or who match the direction they were already heading. Say your fifteen year old and their new friend both skip lessons, or both smoke, or both stopped caring about the thing they used to care about. Some of that likeness was there before the friendship was.
This is not an argument that friends do not matter. They do. It is an argument that the overlap you can see badly overstates how much of it the other teenager caused. Nobody can tell you the split in a single case, including anyone who sounds sure about it.
So removing the friend usually removes less than you hoped. You have taken away the visible half of something that started somewhere else.
Change the conditions instead
You have almost no leverage over who your teenager likes. You have real leverage over the setting.
- Host. A friend you dislike is much safer in your kitchen than in a park you cannot name.
- Set rules about behaviour and place, not about people. What time home, what is allowed here, and where they may be are enforceable. Who they may love is not.
- Fill the calendar in a way that competes rather than forbids. A job, a team, a weekly thing with a different set of people.
- Keep transport in your hands where you can. Being the driver is the cheapest form of information there is.
- Stay boring about it. Every strong comment you make about this friend buys the friendship a little more meaning.
Time together is also harder to arrange than it once was. The Bureau of Labor Statistics time use survey for 2025, released in June 2026, found that 30 percent of Americans socialised on an average day, against 38 percent in 2015, and that daily time spent on it fell from 41 minutes to 35. If you want a different set of people in your teenager's week, you usually have to build the occasion rather than wait for one.
The line that is not about taste
Most of this page is about disliking a friend. Some things are not a matter of taste, and they are worth setting apart clearly. Anything that is hurting your teenager. Anything involving an adult. Anything they are frightened of. Those are not questions about whether you approve of someone. They are questions about safety, and they belong with your doctor, a member of school staff you trust, or your local services rather than with a house rule.
A worked example, for illustration
Melissa started spending most of her time with a girl her father found rude, and who he was fairly sure had been suspended in the autumn. His instinct was to say she was not to see her outside school.
He did not. Instead he said the friend was welcome at their house, set a firm time for being home on weeknights, and offered lifts both ways whenever the two of them wanted to go somewhere. He kept his opinion of the girl to himself.
Over the next four months he learned more about what the two of them actually did than he had known about Melissa's previous friendships. Some of it he did not like, and because he could see it, he could set specific rules about it. The friendship faded that summer for reasons that had nothing to do with him.
What this page cannot tell you
Whether this friendship is doing your teenager harm. From outside it, and especially from a website, that cannot be judged. What can be said is that the tool most parents reach for first is the one most likely to cost them their view of the situation, and that the alternatives are duller, slower and much more likely to work.
Common questions
What if I genuinely think this friend is a bad person?
Separate the behaviour from the person and act on the behaviour. Rules about what happens in your house, what time your teenager is home, and where they are allowed to be are yours to set and are enforceable. A judgment about somebody else's character is not enforceable, and stating it out loud usually just moves the friendship somewhere you cannot see it.
Should I speak to the other child's parents?
Know first that this is close to irreversible. You cannot unsay it, you have no control over how it is repeated between the teenagers, and your child has to keep going to school afterwards. Some families handle it well. Some do not, and it lands entirely on your teenager. This site will not recommend it in either direction, because the outcome turns on things it cannot see from here.
What if the friend is someone they only know online?
For a lot of teenagers an online friendship is a real friendship rather than a substitute for one, and treating it as fake is a fast way to stop hearing about it. Two things are not matters of taste, though, and they are worth saying plainly and early. Anyone who is cagey about their age, or who turns out to be an adult, and anyone who asks for photos. Both mean block and tell an adult, and neither is a rule about which friends are allowed.
They have changed since they met this friend. Am I imagining it?
Probably not, but the cause is harder to pin down than it feels. Teenagers usually choose friends who already match where they are heading, so the change and the friendship often start in the same season. That means what you are seeing is real and the arrow may not point the way you think. It is a reason to be interested in what changed rather than certain about who caused it.
Do I have to pretend to like them?
No, and teenagers detect performance quickly. Ordinary politeness is enough. Feed them, learn their name, ask them one question that is not an interview, and keep your assessment to yourself unless it concerns behaviour you are prepared to set a rule about.
