My DS had a period of hypomania last week, and I've quickly put a plan in place with our Dr. AH thinks all can be solved with a walk outside (I agree it's an important strategy, but only part of it), and that will make him snap out if it.
I'm being ignored. If I walk into a room, he leaves. No chance of him being physically aggressive, just passive-aggressive.
Every time he does this, I just say 'really???' Grow up!!' to him in my head. Sometimes I treat it like a game, other times it brings me to tears.
