I'm shy with people I don't know so well and I don't want to interrupt them. There are times when I wait till they finish, I'm ready to tell something and then someone else starting...at the end everyone thinks I don't have anything to tell. That's not true, with friends and relatives I speak too much and I don't even think about interrupting them, we just talk!!!
EDIT: What I'm saying is that maybe shy people are more respectful to others and when they aren't it seems like they're rude...I really don't like to interrupt:riiight:
