When I was in 8th grade, I decided to spend the whole academic year wearing shorts and a t-shirt to school, and I did it. I grew up in New York and we got plenty of snow that year, so it was a weird and completely pointless thing to do. It was fine, though. After a while the cold stops bothering me, partially because I got used to it, but mostly because of the nerve damage it caused.
I bring it up because we all made stupid fashion choices when we were younger. Some of us clashed colors, and some of us caused enough damage to our skin that we had to see a doctor about it who prescribed wearing pants. Two equally foolish paths.
But, hey, at least I wasn't that idiot who wore knee-high socks, although in retrospect that would have been a good idea.
