Curfew

The rule at my house is a rule my dad started with me:  Be in the house at curfew.  If you decide to stay out past curfew, the next time you must be in one minute earlier for every minute you go over.  Simply put if curfew is 11:00 and you stay out until 11:15, next time curfew is 10:45. For repeat offenses the rate goes to two minutes for every minute, and then three.

Also, decide in advance which clock is the offical curfew time and let your child know.  That way you avoid the excuse, "Well, my watch says..."

Discuss with your child ahead of time what events warrant breaking curfew, for example car problems, and when to call to ask for an extension.
