I called it last night.

Staying up way too late and Middle Boy can't go to school because of a migraine.  This isn't the first time it has happened this year.  Not even only the tenth.  This is time THIRTEEN.

Am I aware of the truancy policy?  Yes.  Do I know that not going to school is a violation of his probation?  Yes.  Does he know?  Yes.  Does it matter to him?  Yes in words.  No in action.

He won't do it again (as said for the thirteenth time).  He will answer to the consequences.  Of course.

Up until now I have had a hard time with letting this go.  Not understanding why he doesn't care.  I can't worry about it anymore.
