Daughter's line recently has been, "I'm 24 years old and I should make my own decisions. You can't control me."
Yesterday evening I made a list of all the tasks that have to be done here through the week. I put M by the ones that I have to do, and left the rest blank. I handed it to Daughter and told her she needed to mark the things she would do to contribute her fair share to the household. We took turns choosing things. She has now chosen pretty much the same things I was asking of her. Now, though, it is her choice. Now she can't complain that she has to do everything around here.
Will it work? Hopefully for a few days.
