At my school there are things like boys ganging up on the one or two girls who are playing basketball or not letting the girls play. That has happened to me a few times. One time one boy started untying my best friends shorts.
Sure they were just decoration but he touched her without her consent.
He said later it was a joke and when I said touching someone without their consent isn’t a joke he was like, don’t be such a feminist.
He also didn’t get into that much trouble.
And my friend,she was so freaked out. We all were.
