One of the tools that a lot of parents have found helps, is we use a code word or a pattern of talking with our kids to help them get out of a social situation that is uncomfortable This might be because of alcohol or drug use or because there is sex going on that the teen doesn't want to be a part of. As a parent, you really want to help your teen get out of a situation that is bad like that. So one of the ways you can do it is arrange for a code word they can use in which you will start a conversation and say, we need to go now, you need to come home with me. They don't even have to ask you, they said the code word. "How is aunt Mary?" If you don't have an aunt Mary, that's the code word, then you can say, "She's at the house waiting. Why don't you come home with me, so you can come see her?" In today's age, with cell phones, even more important thing is to have the ability to call you up and start an argument with you in which you are telling them to come home and clean a room, do their homework, or something else, and they need to come home right now. You pick up the phone and they start talking to you like you are having this argument, you just go with the flow and say, "Okay. I'm going to come and pick you up right now, where are you?" Or if they have a car, they can come home, but that gives them a social device to extract themselves from a social situation where they don't want to be there. It's a great trick as a parent to support your teen to get out of an uncomfortable situation.
