You'll apologize if you have too

In this scene, I think that Wallace did run away from his problem. He was scared that he was going to get into some sort of trouble for throwing his neighbor into a pile of mud. I think that he decided, that hiding out and seeing his daughter at the same time might not be such a bad thing. When Kim said "God do you know how boring this kind of thing is now?", as a reader this kind of got me thinking that this may be the reason why Kim and Wallace are no longer together. Is because this isn't the first time that he has pulled something like this before, and that this is like a regular thing for him. Kim doesn't want to have her daughter growing up around something like this, where her father is always getting into some sort of trouble.
In the second scene, I think that Wallace started to face reality. I think that after seeing his daughter and speaking to Kim, he started to realize that may be the things I am doing now is getting old. Especially after the comment Kim made "God do you know how boring this kind of thing is now?" I think that Wallace decided that may be he was just sick of the way he was acting and that may be he needed to grow up and start taking responsibility for his daughter. I think that the first way he realized that he wanted to make things right was by apologizing for what happened in the estuary.
