Okay kiddo, pain compliance is when someone hurts you on purpose to make you do what they want. It's like when your big brother pulls your hair to make you give him your toy. Pain can be really scary and make you want to do what the person hurting you wants, even if you don't want to. But hurting someone else is never a nice thing to do, so it's important to talk to a grown-up if someone tries to use pain compliance on you.
