My son doesn't want to go to sleep

Well, my son is 15; so he's a big boy now and he should know that if he doesn't go to sleep now, he will be tired tomorrow when the alarm clock rings at 6 AM to take the bus to high school (it's 10 PM). He's near me as I write this note, so I hope that he reads it and GOES TO BED !!

Ah the vigors of youth! Let him be and let him learn through his mistake.  The more you tell him, the more he will resist.  Think of your own childhood...  We all have different sleep rhythms and patterns.  At that age, he has more vigor than most of us.
