That's about the best sentence in the realm of parenting. Kids often learn that saying the right words will suffice instead of having the right behavior. ie, they can say sorry and not really be sorry.
I grew up with 8 siblings. Mom used to look at us and ask how we'd like it if she gave one of the other kids permission to do to "us" what we just did to someone else. That was a terrifying thought. lol.
