Random little anecdote: A kid at my school got suspended for 2 weeks for calling the school librarian hot. This happened years ago and it was a big scandal lmao
Two weeks for that sounds excessive. Imagine if they said that the librarian was thicker than a bowl of oatmeal, that kid would be in prison to this day.
Suspension at all is a bit over the top for some dumb thing a kid said. Maybe have them write an essay about why it’s not something you’d say to people.
