A group of teens, all 16, are hanging out together.
As they conversate, one girl admits she’s been having terrible menstrual cramps all day long and it’s extremely tender to even so much as poke her stomach.

Well, one of the teenage boys, being a teenage boy, thinks “it can’t possibly be that bad” and decides to test this out by kicking the girl in the stomach where she pointed to.
He didn’t kick her all that hard, not even hard enough to leave any sort of mark, but the girl, being so sensitive, doubles over in pain and then retaliates. She beats the boy almost to a pulp until the other boy stops her to help his friend.

The bruised boy on the ground shouts out “if it hurts all that bad, how can you move like that!?”

The second girl, who has been calmly watching from the side, answers “the movement was probably agony too! But she has her priorities!!!”
