Daughter used up her ability to cooperate and be helpful with the books. She's "too tired" tonight to take out the recycling, empty the dishwasher, and take care of the cat boxes. I told her I thought I was going to be "too tired" to do anything for her for a while. After I took out the recycling and emptied half of the dishwasher, she came storming out to finish her chores. I was not impressed.
When I take a step back, I think she is exhausted from being cooperative and responsible and putting on a good face for others. When I'm in the midst of it, I'm frustrated by the fact I never know when I'll be able to count on her or for how long.
