This is a fun topic G.! Here is some of the things I dislike:

A. People who can't stop checking their phone, starting early in the morning.
B. Curly macaroni. I will not eat anything done with this kind of pasta. Brrrr the shape of them just rubs me the wrong way. Yes weird don't ask
C. Sweet sweet fragrance perfume on people. I feel like I am close to fainting when I feel this sort of smell.
