Hah how about NO.
I'm a nervous person in general, so in front of crowds and classes, I get nervous but I can still pull off a decent presentation. I've never had an embarrassing moment in front of people or whatnot.. but I just hate it with a passion.

I had to do so many class presentation projects last year for my ITIT class and now I'm going to be doing a few for my Zoology this class this year.

Even with so much experience, I still shiver in fear of being called up next.
