"Sticks and Stones" . . .
. . . is a load of bullshit. A broken bone was easily ten times better than being teased and bullied on the daily. Once a bone is broken, normal humans start to get a sense of what they're becoming and back off. But the words, they'll just pile up until they block out all the light in the Universe.
Pro tip: Don't ever tell a kid "sticks and stones may break your bones, but words will never harm you." Say, "Fuck them; that sucks that they're being assholes!" Say, "I love you."
