Why didn't Miranda come home from camp and contact Via?

Miranda didn't call Via because she didn't want to talk about serious things like her parents divorce, and she didn't want to be asked.

When I got home from camp, I called Ella right away to make plans with her. I don't know why I didn't call Via. I guess I just didn't feel like talking about stuff with her. She would have asked me about my parents, about camp. Ella never really asked me about things. She was an easier friend to have in that way. She wasn't serious like Via. She was fun. She thought it was cool when I dyed my hair pink. She wanted to hear all about those trips through the woods late at night.
