Where I come from, it feels like it sometimes, but they also look somewhat down on people who can't be silent even if you whack them in the head. I got this guy in my math class who always have to talk and answer everything. If someone else answers, then he comments it afterwards. So annoying <_< . I really didn't wish people thought that way though, I know many cool guys who is shy, and I think it's unfair that others look down on them.
It's not really something that bothers me though. I like talking with others, but I can be quiet if I want to be quiet. I also have a job that doesn't allow me to be quiet because it wouldn't make any sense if I didn't speak to others.
