Anger/Reason
One father decided that the best way to handle kids coming home past the negotiated time was to simply explain that he was tired and would talk to the child later about the broken agreement. Then the next time the child asked to go out, he would say, "Oh gee, I'm just not up to worrying tonight. Why don't you stick around?" or "I'm sorry, you can't go out tonight honey. I need my sleep" (Cline & Fay 200). Anger causes confrontation, but sometimes teenagers will listen to the practical effects that their lateness creates for you. (The humor in the responses also breaks down communication barriers.)
Contact List
"Have your sons or daughters leave a list of numbers where they will be and then let them know that you will be setting your alarm for the time they are expected home. You trust them, so it is no problem to go to sleep when they are out; however, should that alarm wake you and they haven't called to let you know they will be home later, then you know something is wrong and you will start calling everyone on that list, ending with the police. However, if they are home on time, they can simply slip into your room and turn the alarm off before it wakes you" (Cline & Fay 202).
Trust
Create a relationship of trust by letting your children know that an important aspect of a curfew is for them to follow through on their promises. This is a different focus than"I don't trust what you'll be doing" or "I don't trust your friends." The reason for having a set time for coming home becomes more about the children showing you they are responsible and trustworthy.
Model
Try to be organized and reliable with your own time to show your teen that you are serious about schedules and take other people's time seriously.
Two-Way Street
"We're often most effective when we simply let our teens know what our concerns are. For example, when our teen comes home late, we could say, "I hope this doesn't happen again because I think it stresses our relationship. And you're way ahead if our relationship is good. I think that when you do things that stress me out a lot, it doesn't work out well for you in the long run""(Cline & Fay 203).
