Hmmm, Tim. Up until a couple of weeks ago when I basically demanded that she either cook OR clean up after dinner, you just desribed her normal Monday night. She'll often say to me, "I'm beat. Mind if I just take a bath and read?" My answer is always yes.
I was going to fix dinner (going out is not really an option during the week), and I'll even clean up afterward, since it's her birthday.
The coupon book idea is nice, but basically, all she has to do is ask, and I usually say yes.
