I notice a lot of mouth breathing, people will get up and move away from me if they've been sitting nearby, I get loads of veiled comments about fish or "It stinks in here/what's that smell/what died?" kinda comments. People in my class sit and make fish jokes and burst out laughing - I guess they think I don't know!? Then I have some of them posting memes on FB about fish/dirty genitals. The other day, I had one of the doctors up at the hospital take a really long accentuated breath in, then breathed out really loud and fast - while giving the nurse a knowing look. Oh and people open windows around me a lot too, or turn on fans. :(
