When you get wet, You get sick. Nobody wants kids to be sick in their classroom. Rooms get smelly and humid. Students and kids will clean up after. Sick kids could infect teachers. If teachers get infected, Everyone in the school will get infected. Also, If kids are wet, They don’t focus as well as they should.
Is it a Zoo.

Ok so I was not much better when I was your age, But a least we were allowed to sit indoors and eat our lunch in some sort of basic civilised fashion and we certainly weren't forced to stand around in the rain getting soaked.
