I used to be real shy! I've gotten a lot better but I still stutter and shy away when talking to a waiter or if someone I feel is either insincere with me or is judging me for some reason.
Whenever they feel grotty. That could mean up to 5 times in an hour, or not at all for a week. (Ok ok! So I'm a bit of a feral!! Then again, that's what makes me fit in so well around here... )
Do you like having pins & needles? (If by any chance you do, give us a hint as to why.)
