What do you call that place where the kids are still too sick to do normal stuff, but not too sick to annoy each other?

My two little ones are playing beautifully together, I really don't want to interrupt. Can't rid myself of the conviction that a 6yo needs to learn to read, however.

We have been working on school for three hours. One child is done. The other hasn't completed a single subject. Sigh.

My kids are trying to figure out if all three of them will ever have ages that are prime numbers in the same year.

Had insomnia last night, so spent 3 hours making schedule for MCT Town. That's not strange, is it?
