Three is old enough for a butt-whipping.

Me: Luca had a rough afternoon. His teacher said another kid pushed him down twice on his bad knee, and he won’t walk like he was this morning because his knee hurts.

Paolo: Oh yeah? When that kid gets older, like three, I’m gonna punch him!

Me: Paolo, I am so proud of you for wanting to protect your little brother. I am also happy that you know it would be wrong to rough up a little guy. Even though you’re mad at Luca’s classmate for hurting him, hitting is never the answer. Tripping is so much easier to get away with.
