Discourteous Dwight

In this short section of the book, a lot of Dwight's true identity was revealed. I noticed this especially when he went out of his way to hit the beaver on the street while he was with Toby. I felt particularly sorry for Toby because he is seeing a completely different side of Dwight- that his mother isn't seeing, and may never see. Hopefully Toby stays strong and does the right things to properly deal with Dwight. I wonder what he'll tell his mother, if anything.
