Haha, math contests? No, not at all. Again, I enjoy math, but I'm not THAT good at it. The only difference between me and the average person is that math is not a chore for me, but rather a pastime. Granted, I'm lazy, so I dislike doing any homework, but if I had to choose a subject to study for an hour, it would be math.
Why yes, I do remember that incident so long ago. I recall I was baffled at what you were asking. I, too, am somewhat fascinated by the icosahedron, although perhaps now, as I am no longer taking geometry, it's just a username and nothing else. Hehe.
Having been on a fairly large hiatus prior to August, I haven't been able to keep up with all these name changes. You'll have to excuse me for wondering who you were; rest assured, I definitely would have recognized "SmArticuno." =P
