And again, I ask why

Yesterday Noah had another "incident" at camp. He was in the bathroom with another boy. No idea why both were in there since only one is allowed in at a time. And apparently it was only for a few seconds. But, he made the most of those few seconds and pushed the kid into the wall and put his hands on his throat.

When Noah was asked why he said "because I wanted to" and because "my brain told me to."

This scares the hell out of me!

Even Noah agrees he wasn't provoked. Nothing happened that in any way can "explain" this.

I know no one has an answer for me, but all I can think is "why" and what does this mean for the future?

Or am I just overreacting?
