Oh, OH! I forgot another one...
In 2nd grade I learned the trick ~somewhere~ of pulling a kid's chair from underneath them before they sat down. Well there was this girl who I was pretty good friends with (we had a good conversation about the book Mickey and the Giant) and I decided it would be funny to try it on somebody, so I asked her to stand up. She asked why and I just kept telling her to stand up. Well evidently she trusted me a good bit so she stood up and when she went back to sit down, she fell flat on her butt! I of course laughed but she didn't think it was funny, and I had to apologize over and over for that.
Then there was the time in the same grade we were taking a spelling test and I was superb at spelling (my mom had taught me well at home) so needless to say I was EXTREMELY bored in-between words because I wrote them down immediately and just sat there the rest of the time. So I ended up looking inside my folder to find out what the next word was because I couldn't handle the suspense. Of course the girl next to me thought I was cheating and I had to explain to the teacher that I wasn't, I was just bored. I'm not sure if she believed me but I think she let it go. haha.
Then of course there's the lovely tale from third grade where a girl who always used to sing the name game for me was a bit chunky, but she was really cool and I always found myself doing something in exchange for her singing it using my name. Well for some reason her ability to remember things came up and I said, "Cuz you're an elephant!" And all the kids immediately freaked out on me and were like, "Ummm... that's not nice." And I was all, "No, cuz elephants NEVER forget! Arrgh..." And she was all, "That's it, I'm never singing the name game for you AGAIN!" heheh.
And in the same grade when were learning about atoms I had the girl next to me cracking up because I was drawing little naked "Adams" on the desk. haha. Boy, those were the days.
