WTF?

Today my tooth ached slightly at the gum line whenever my lip would brush up against it. There was nothing too bothersome about it, because the ache wasn't very strong and when I rubbed it with my finger it didn't hurt. But I still wanted to see what it was.

Once I had the opportunity, I went to the mirror in my bathroom and examined the situation. Apparently a quarter-inch long beard hair I had shaved off had wedged itself between my tooth and my gum.

Seriously, wtf.
