As a socially anxious loner, I didn’t go to prom. Didn’t end up feeling much like I was missing out either. I had been to a few school dances in the past and they always made me very uncomfortable and I didn’t find them fun. I didn’t like how much of a big deal they were made out to be. The one time I had fun around a school dance was when I was hanging out with some people either beforehand or afterwards (can’t remember which) and that part of it was fun. The dance itself wasn’t.
OP went nuts in the comments of the original. I can’t remember the details, but they were saying things about how they were incredibly offended and wanted to DNA test their son for not being thankful for the gift. And some rambling tirades about the grandmother or something. It was very bizarre.
