Try to Avoid Repeated Criticisms of Their Friends
I personally don’t think repeatedly criticizing your child’s friends or pointing out that they’re bad is going to be a successful strategy. Again, adolescents are developmentally at a place in their life where they’re defending their friends. And so it’s very difficult for a parent to turn around and say, “Your friends are no good,” and expect to have a conversation. Your child’s natural urge is going to be to protect his or her friends, whether or not they know you’re right. Realize that criticizing your child‘s friends is like criticizing an aspect of your child. It’s going to meet with the same resistance and hostility—even if what you’re saying is true. And all it will do is further alienate your child from you.
Make Clear Statements about Behavior
I think if you don’t like your kid’s friends, the most effective thing to do is state: “I don’t like the way they behave.” That’s the first thing you can say. “I don’t like you hanging out with kids who get in trouble, because you get in trouble with them.” Can you say this every day? No. But you can say it once in awhile. Be sure to simply state the facts. State what you don’t like about their friends’ behavior. You’re not judging them. As a parent, I think you want to be a little smooth about that. You could say, “Look, I’m sure your friends are great to you. But they all smoke pot and they all get into trouble. If you hang out with them, you’re going to get into the same trouble.”
Remember, when we’re having conversations like this with our kids we want to keep our observations on a level we can see. By that I mean talk about things that are recognizable: “I don’t like that Jackie got arrested for shoplifting. I don’t want you to get arrested for it, too. I don’t like that your buddies all use drugs because I don’t want you using drugs. I don’t think it’s good for you.” Make those observations and keep it simple and direct.
Use Structure
I think that structure can be very helpful when dealing with your child’s friends. In other words, if you don’t like the kids he’s hanging out with, then don’t let him go out on school nights. Try to have more control over where he goes and what he does. If he says he’s going to the football game and then you catch him down at the mall with those friends, that’s his choice. He chose to go some place which you didn’t know about and there should be consequences.
Set Limits
If you know your child’s friends are engaging in behavior that isn’t in line with your values, then I think you should set limits on how much time they spend with those kids—or whether or not your child can see them at all. If his friends are breaking the law or doing things that are unhealthy, you can say, “Maybe they’re your friends, but I’m not going to let you hang out with them.” With a lot of adolescents, defiance becomes a big problem. Many of the kids I dealt with would climb out their windows when told they couldn’t go out. But again, you set the standard as the parent; you set the expectation. If your child doesn’t meet it, at least he knew there were standards and expectations to begin with, and now he will have to face the consequences and be held accountable for his actions.
Going Out on Friday Night is Not a “Right”
All of a sudden, kids hit a certain age when they think they have the right to go out. Well, I don’t think so. I think kids have to behave responsibly in order to earn the right to go out. And you can say, “I’ll let you go out if you show me that you’re trustworthy.” Behaving responsibly does not include hanging out with kids who use drugs and drink—that’s all there is to it. I also think going out on Friday or Saturday night is not a right; it has to be something that is discussed every week. My son used to come to me and say, “Listen, Saturday night we’re all going up to the lake. Is it okay if I go?” Saturday night was not his automatic night out. Instead, that was negotiated each week, and the answer wasn’t always “Sure.” As a parent, I think you should be saying, “What are your plans this weekend?” Your child should know that they have to have their plans Okayed by you first, and that they have to behave responsibly in order to earn the privilege of going out.
Talk to Them about Mean Friends
What if your child is hanging out with kids who treat him badly? Know that he’s hanging out with them for a reason. He’s probably afraid of them so he’s trying to become one of them. When kids are afraid of bullies and other kids, one of the options they have is to join the group and become a bully. Because even though these kids are mean to him, there is a sense of safety there. The deal they make is, “I’ll let you be mean to me and tease me, but you won’t abuse me or beat me up or take my lunch money any more.”
But I think if your kid’s friends are mean to him, the kind of questions you want to ask are, “What are you trying to accomplish by letting people treat you this way? What are you getting out of that?”
Try to have an adult conversation with your child. You can say, “Listen, you have choices; you don’t have to hang out with these kids. You don’t have to be a victim. I can get you help with this.”
