My Current Bane
Several days ago I got a canker sore on the inside of my bottom lip. It probably came as a result of biting myself ever so slightly - I have a tendency to bite myself. I did not notice this bite, but the canker sore grew and became swollen. This in turn has led me to bite my lip again, which makes the area swell up even more. And so on and so on...
Canker sores are just pure evil. They can sure ruin your day.
