Talking to your boss/manager - not a problem, they are very approachable
Being with a group of strangers - fine with this, just slowly say hello here and there. When its all strangers then often most people are nervous. If they are already friends, then mostly they are welcoming if I make an effort
Being with the opposite sex - love it now, missed out on it too much from being a girl-shy teen
Parties - few beers, ok
Giving a speech - would hate this with peers, can talk in front of students
Meeting a date's parent's - lol, at the nursing home?
Asking for a date - I'd be terrified but would only ask someone I really, really liked, so would do it
New job/New school - Ok with this, I typically think 6 - 12 months ahead and imagine myself comfortable in the job
Interviews - terror. last one i stuffed up badly. went home and curled up in a fetal babbling mess. also forced myself to wear a tie to it. horror
Saying something stupid - do this everyday at work in front of the class. laugh it off and move on. not an issue anymore
