Trying to co-parent

I just got off the phone with my wife. She gave me a whole list of demands. She wanted her support check early. She wanted me to pick up the kids, supervise their homework, take them to after-school classes, do a car swap, etc. She is going away for the weekend, and wants me to take the kids all weekend. I agreed to all of it.

Then she tells me about one kid is learning the letter T in kindergarten by everyone in the whole class bringing food tomorrow that is spelled with the first letter T. She wants me to check the sign-up sheet at school, find a food that none of the other 21 kids are bringing, and take the kid to the grocery store to buy that unique T food.

The whole exercise seems like a bad idea to me. The kid already reads at a 2nd grade level, and doesn't need to learn the letter T. The class spent all last week learning the letter M, and all this week the letter T. The tasting is also dangerous, as the kid has allergies.

Anyway, I said that I would give her some T food but I couldn't guarantee that it would really be unique, and I couldn't guarantee that I would goto the grocery store because I might already have the food.

Then my wife gave me a lecture on how co-parenting with me is impossible. She says I refuse to give her a straight answer to a question. Sigh. She is probably writing a complaint for the court right now.
