I can smell you. Everyone can. Please for the love of god, use deodorant.
EDIT: Thanks for the Gold/Silver! To the people asking why I wouldn’t say this to a student, the answer is twofold:
1. Puberty is a smelly ordeal, and a lot of the kids can’t help it
2. Because god forbid it’s not their fault (infection, a cultural thing, or improper washing of clothes), you don’t want to alienate that student forever.
