Rose Colored Glasses

Apparently I've been wearing them. All these years I figured Ashley and I were very close and she'd confide in me about anything. But lately, she's totally shut down. She stays in her room, she won't talk about anything. I know she thinks her dad and I are stupid. Evidently, neither one of us has ever lived a "real life" and we know nothing. But at least she used to talk to me.....but not anymore. Should I be worried? Should I leave her alone? Should I go through her things? I mean, she could not understand why I would call her when she wasn't home by curfew....and just didn't get it when I was really ticked off that she wouldn't answer her phone. When I tried to reason with her that a parent worries (and generally our imagination runs wild), again....I'm stupid. I'm trying really hard to remember how I felt about my parents when I was her age, so that I can some what understand her, but it's hard. I thought we were close, but right now, I guess we aren't.
