My Car Was Broken Into Yesterday

I can't understand why someone would want to brake into someone's car and only take my sun glasses, a cheap ipod transmitter, and all my insurance, title and registration paper work out of my car. They didn't take some CD's I had in there or Spencer's sunglasses. I wonder if it was a girl who did this. The only damage to my car was the broken triangle window in the back. Anyway, I'm ok and everything is getting taken care of.
