yesterday i accidentally bit my lip like. really really f**king badly, there was blood all over my hands and mouth, and i didn't even notice until in math class someone was like "why is your mouth red are you wearing lipstick"
But it was funny as hell
"UHHHH MS [teacher name] CAN I GO TO THE BATHROOM IM BLEEDING PROFUSELY"
"yeah be quick"
"OK THANKS" *immediately darts across the entire classroom and through the door in 0.2 seconds*
