once, my friend (let's call him 1) wasn't feeling well. The teacher was like "nah you'll be fine" after he asked to go to the bathroom. 1 ended up throwing up on top of like 3-5 seats, and the entire back row kids had to be moved to the front. 1 ended up going home. I was right next to him and I legit got up to get my pencil sharpened when I dodged the vomit. (sorry for the essay)
