I walked into a lab one time, feeling like I was on deaths door, and the TA took one look at me said “As long as that’s not a hangover, I’ll cover for you.”
I said “Believe me I WISH this was a hangover” he marked me present and I immediately went home and slept for 2 days.

Signed, a person who somehow came up with “dear hello, I am sick and not sure if I’ll be alive to come tomorrow and I’m sorry, best slutantions, [name]”.
