Oh, god. I met one of those in high school. Like feel his teeth around your mouth. You'd think someone along the way would have figured out a way to guide him to something more pleasant.

Unfortunately, 16-year-old me didn't know how to approach this. Instead, I was at my after-school job when it was slow and was chatting with a coworker about this very topic, when unbeknownst to me guy in question has just walked in and overheard me saying he was a terrible kisser. I've felt so guilty about that for years now, even though it was unintentional.
