I was getting off the bus on my way home from work, and over the course of five seconds, I went from, "La la la, must cross the street, boy, my bookbag is heavy, la la la" to "Hey, I'm going to get a nose ring--RIGHT NOW!" I literally swerved, heading over to the conveniently placed tattoo and piercing parlor a block from my house and went in and signed a piece of paper and had a guy named J.J. shove a sharp piece of metal through my nose. It's actually a stud, not a ring. It's awesome.
I'd been thinking about getting one for years, but hadn't quite committed to the idea.
