I'm sure that there were a hundred embarassing moments throughout my school experience, and I'm equally sure there are many more to come. However, I will remember to this day the one thing that really caused the worst embarassment for me. This happened in the first grade. I had a really "serious" boyfriend (we "went together" for the entire school year).
One afternoon our class was on the playground, when my little boyfriend decided to kiss me. He kind of took me by surprise, and of course, all the other kids were oohing and aahing over it. I was mortified! I was so angry with him, that I wouldn't speak to him the rest of the day. I laugh at it now, but I really was so upset over that kiss.
