How come Vada didn't like Shelley?
Shelley was a little spacey, but all in all, she seemed a decent person. I understand the rivalry thing or the feeling of resentment, but some step parents can be real mean and nasty to their kids. If it wasn't for Shelley, the dad would have never come around. Shelly really stood up for Vada. Towards, the end, Vada started coming around, but she should have been more thankful.
"Duh. You're the idiot. Not me."
