Gratuitous Domestic Posting (TM)

Every now and again I discover just why my parents told me not to do certain things that I otherwise could not see causing any harm.

Here's one: My three year old can cross her eyes. She does this when she's feeling particularly goofy. Now I never believed that one's eyes would really get stuck that way, so couldn't see the harm in doing it myself. But now I understand - looking at her like that makes me nauseous. Bleh.
