I enjoy getting canker sores I don't get why people hate them so much, I always get a sense of excitement when I wake up in the morning with a fresh ulcer on my lip, and the more the better. I like having a warm, iron-ish tasting sore to lick and play with to keep my tongue occupied whenever I'm bored, kind of like sucking on a mint but better. Sure it hurts a little when I eat or accidentally bite on it, but the swelling makes them all the more fun to suck on.
