I overhear my daughter, 5 years old and weighing 40 pounds right after a big bowl of pasta, and eldest son, 13 years old and nearly 100lbs, in her room. I sent him in there to tell her that she needs to do her homework.
Luc, “Ow! Ow! Stop it! You have to do your homework!”
Annabelle, “I’ll stop once you say that you’ll do my homework for me.”
