some muggleborn like “i want to be an astronaut when i grow up!”
wizard kids like “wtf is an astronaut”
"oh you know…the people who go to the moon"
implying that magical children would know literally nothing outside of the wizarding world
I get that wizards might not know some everyday muggle facts, but they live in a society with Werewolves. I am pretty sure wizards know about the moon.
