Chapter 48

Matt old friends, and some other people invite him to some partys but they don't want Ursula to come with him because she just doesn't fit in.
But Matt doesn't want to go there without Ursula.
He prefers being alone with Ursula and going somewhere else with her.

I think Matt doesn't want his old life back and that's the reason for him not going there.
I like reading that chapter a bit because Matt stays with Ursula.
