Hair pulling
A six year old comes crying to his Mother because his little sister pulled his hair.
"Don't be angry," the Mother says, "Your little sister doesn't realize that pulling hair hurts."
A short while later, there's more crying, and the Mother goes to investigate.
This time the sister is bawling and her brother says...
"Now she knows."
