Of 3000 Americans surveyed 41% had a fear of speaking in front of a large group of people and 32% had a fear of heights.
I would fall in the group that had a fear of speaking in front of a large group of people.
Which is not entirely true. If it is planned then I am a goner. I will mispronounce words, make jerky movements, quiver my lip, and maybe click a clicking toy in my pocket to have something to do with my hands.
However, if I blurt about a bit of wit or wisecrack that just came to me. It seems sometimes I have perfect timing.
I have had many teachers glare at me as the classroom students roared.
