When my brother and I were kids. My brother had a bad habit where whenever we fought he would bite me, hard. It hurt like hell.
One day, our dad bit him as punishment. Hard enough to leave a mark, but not enough to cause any actual damage.
My brother never bit me again. True story.
Anyways, today a day care worker was sent to jail here for doing exactly what my dad did, to my brother, to one of her kids.
We've become too soft.
