I just asked my four year old daughter to get dressed for the day. She said she wouldn’t get dressed because her brother wasn’t getting dressed yet. So I yelled to the next room for him to get out of his jammies and get dressed. I then re-asked my daughter to go get dressed and she still (politely and cutely) refused.
So we had a long discussion about “negotiating in bad faith”. I don’t think it sank in though.
