Math Teacher's Body Odor

My math teacher's body odor is seriously intense. I sit in the front row, and every time she walks over during class, I have to hold my breath or cover my nose, otherwise I feel like I'm going to throw up. She especially likes to wear clothes that are almost sleeveless and a bit breathable, so her scent just spreads everywhere. When she's writing on the blackboard or waving her arms, it feels like an air attack. You have to cover your nose quickly, or the memory of the smell lingers for a long time. A classmate joked that she waves her sleeves without taking clouds, but leaves behind a cloud of body odor. No other teachers are like this, I suspect she might be going through menopause. And today, she was discussing problems with a student who also has a severe body odor issue, standing together – it was just double the stink. That's when I regret sitting in the front row the most.
