At any rate, I decided this morning to remove my nostril piercing. It's been a nice 2.5 years of having a glittery thing in my nose, but
(a) I've decided the line of nose is much prettier without it and
(b) This will solve the problem of always having the little metal dangly bit that goes on the inside of the nostril turning down and appearing to be a gray glob sticking out the end of my nose.
On the other hand, I'm not entirely sure how long it will take the hole to close and it is a touch disconcerting to see the empty hole when I look too close. Ah well.
