I'm glad you're being really tough because it's empowering me to take what's mine, and some of it really IS mine, but to leave him his.
In reality, he would NEVER ask me what she needs to get done. He doesn't give a flying eff if she does her piano homework but I'm the one who sees the piano teacher on Tuesdays.

You're right though, and I want you to call me out on it if you see it continue. I can't keep picking up his mess.
