We all know that little kids can be a bit gross now and then. They're obsessed with farts, toilet hummer and most of them will happily feast on their own boogers, regardless of whether they have an audience.
For this reason, primary school teachers will always be heroes. They do so much for our children, and they are rewarded with bum jokes.
Still, working with little kids is not always the disgusting germ fest you may imagine. In fact, some children show considerable politeness when managing their bodily functions.
One Imgur user has proved this perfectly by sharing a photo of a little kid's spelling test.
"Do not touch," says the note, along with a circle indicating the danger zone.
"Is snot, it fell from my nose."
The thoughtful child may have had a drippy nose, but at least she was thoughtful enough to think of her poor teacher.
Top marks for courtesy kid, and with 91% on spelling, good job there too!
