Today, I was talking to Derrek about his emotions and offering some suggestions for controlling them:
If I get too angry, I know how to calm myself down. Sometimes, I get so mad, I do the "Hulk Smash" on my bed, like I'm trying to crush it with my fore arms. The bed is soft, so I don't hurt myself, and I can't break the bed by smashing it. Plus, it wears me out. I'm too tired to be mad after that.
Then I took him outside and let him do the primal scream.
