My Ring

I have this cool ring I wear on my left ring finger. It's a crescent moon with a face, and a ying-yang between it's two points, forming a circle. People keep asking if it's a promise ring, or a purity ring. I think that promise rings and purity rings are stupid. Who are you going to promise yourself to when you're in middle school? And purity rings, how hard is it to just refuse sex? Why do you need a ring to remind yourself?
