#7: 10 Minutes
It’s pretty strange that no matter where you are in the world, some kid at school always tells other students about the alleged “10 minutes of waiting” rule. Is it even a thing at any school, really? Even Urban Dictionary has it as an “unwritten rule,” but there’s no proof that it’s true! Was the 10-minute rule a thing at your school? Let us know back in the comments.

The University Press Online investigated this rule and contacted several colleges about it. Most of the staff said they’d never even heard of this policy, while one said it categorically didn’t exist! So, it’s better to just wait for the teacher unless you want to be sworn at.
