Bad story: I was in second grade and was just starting to get known as a braniac. We would play
Around the World, where you have to go up against each kid in the class and try to answer math problems as fast as you can. I was pretty fast at the four basic operations, and I could beat anybody the majority of the time. I hated the game, though, because everybody made a huge deal of it when I lost. One day when we were doing multiplication I went around the entire class and was so mentally tired that I just let my best friend win as soon as I finished.
Then the next day we did the same thing again, but this time it was on addition instead of multiplication, my specialty. I got through around three kids and then I was too slow on the question "What is 8-8?". The girl I lost to didn't have a reputation for being smart. The whole class burst out laughing like I was funnier than some amazing stand up comedian. The teacher tried to shut them up, but it took quite a while.
I have had a fear of competition since...
Good story: When I was in 8th grade I had a huge crush on one girl that was in a bunch of my classes. I came to gym the first day in second semester and found that she was in that class. I knew she was a soccer player, so I was excited when I learned we were playing soccer for one of the units. I liked soccer too, but I didn't play it. I did, however, hacky sack a lot, which made me look useful in the game when I was actually just mediocre. When we went out to play, I actually scored once so I looked pretty decent at the game.
The next day in science, I walked in and she asked me if I played soccer. I responded that I didn't, but then she complimented me on my talent. It was just a little thing, but it made me super happy for a while. I still remember that feeling...
