So SS17 finds a way to make things all about him, even in his absence.  His bad behavior with his mother was addressed most recently yesterday with his counselor.  Yes, he's in therapy and on meds and still acts like an ass on a regular basis.  So after his Mom had a long discussion with his therapist, I'm guessing his conversation with his therapist wasn't much fun.  Later in the day, he left the house almost as soon as he got home from school, didn't come home for supper and it was nearing bedtime before he showed up.  I'm sure he was expecting a fight when he walked in the door for skipping dinner (he never misses a chance to eat), and not telling his Mom where he was going or when he'd be back.  He didn't get it, although we spent some time talking about things and mostly about him and how he acts.  She was upset with him, but I talked her into letting it go and not taking the bait.  There was no fighting/arguing when he came home.  Yeay me
