Ridiculous conversations

Every once in a while I find myself in a totally ridiculous negotiation with Lena. Here is the first list in what I'm sure will be an ongoing series:

1. Lena, please don't spit milk at the dog.
2. Lena, please don't put sand in your umbrella.
3. No, Lena, you can't eat the oven.

I think I'm in for it.

Me: Lena, it's time to brush teeth. Come on.
Lena: No. I'm still sulking.
