I've had a cartilage piercing for 11 years, but have been toying with the idea of taking it out and letting it close up. Yesterday I was getting my hairs did and I popped the earring out and decided to not put it back in.
I swear 10 times at least this morning, I've reached up to toy with the earring to find it isn't there. Maybe it was my worry spot and I didn't know it, oh well.
