A DMK Production
Your thirteen year-old son, Kyle, is still subject to spanking but, since he turned thirteen, you have tried using grounding with him for less serious problems with good success.
For the past two evenings Kyle has come in late for his curfew without any call or explanation. Kyle was not seriously late either evening (25 minutes the first night and 20 minutes last night) but it was enough that you needed to get Kyle's attention. You told Kyle he was grounded for the next two days. This essentially means Kyle is not allowed to leave the house except for school.
You work from home and would normally be available to supervise Kyle being grounded. You had to run an emergency errand this afternoon and left a note for Kyle to see when he got in from school:
Kyle, I had to run an errand this afternoon. I'll be out for about two hours after you get home. Grab a snack and go ahead and start your homework. Remember, you're grounded.
Kyle seizes his opportunity.
You finish your errand early and head home. You pass by the local park at the end of your street and happen to see:
You pull over and go up to talk to Kyle, He sees you and blurts out, "You aren't supposed to be home yet!"
How do you handle this?
