Another one:

In high school, I was terrible at flirting with girls. Whatever I would do always backfired on me. This is the worst instance I can remember. I believe it was freshman year, it was after school, and a bunch of us were just hanging around. I don't remember how it started, but this girl and I were chasing each other around some trees, and it was fall/early winter so there were leaves on the ground. Eventually we stopped, and she was sitting on the ground, and I came up behind her and threw a big piles of leaves on her head. What I didn't know is those leave hadn't been disturbed in a while and they were sitting right on top of an ant hill. So they were covered in ants, and she ended up being covered in ants.

She never spoke to me again.
