lots of people are shy...lots are quiet. They are not the same thing. My daughter is quiet, but she is NOT shy. Some people ARE both, but you don't have to be both.
You guys are right. Meeting someone at a meet and greet for a minute or two isn't going to tell you much about that person. Still, for someone who is not social...I can see why meet and greets would be very uncomfortable for them. Too many people and nothing but small talk. No time to really chat with anyone.
As for meeting Scott....if he were doing a meet and greet in my area, yes, I'd go. I don't dwell on meeting him. It'd be nice, but it's not that important to me. I'm much more into the music. If I ever had to choose....go to the Creed concert...or go to meet them at a meet and greet??? I'd choose the concert.
