I don't like being the center of attention. It's not the same as being shy. I can be quite open, one on one, but in groups I get quiet cuz I can't focus on everyone at once.
I've been in a couple weddings. Usually I'm so dressed up, made up, and have my hair done up so that I don't really feel like *me,* more like a project I worked on for the occasion that is now on display. Heh. It also helps that you don't have to talk to be a bridesmaid.
I sorta disconnect from the situation until it's over. It's not so bad.
