While driving home from the Great Drain Garage Sale of ought eight, my kids decided they really wanted to play with their cousin J's Nintendo DS. J doesn't like to share it, so he came up with a good reason they shouldn't take turns.
J: You shouldn't play video games, because they make a storm in your brain.
Z: Then how come you play them all the time?
J: Because I like to.
A: Who even told you that it causes a storm in your brain?
J: My cousin K.
Z: How old is K?
J: He's six.
A: I don't think he even knows what he's talking about.
J: Yes, he does! He's really smart.
(This was met by a great deal of eye-rolling and snorting from my daughters.) Then we had a little tangent where I talked to the kids about if they had ever had a brain storm, but it's too long and involved for here.
