Teeth are sharp, kids, teeth are sharp.

Dear Children,

Your teeth are sharp. It shouldn't surprise you--though it always seems to--that your twin's teeth are sharp, too. It would behoove all of us if you did not try to test this by placing your finger in your sibling's mouth. And if your sibling does this to you, for crimoney's sake please do not close your teeth on the sweet little finger. It hurt this time. It hurt the last 100 times. Ever heard of Pavlov, children??

Love, Your Mom.
