I guess humans have pet peeves or some say 洁癖
I have loads.

- i can't stand going in the toilet after someone did his/her business, esp a guy.

- i don't lie straight on my bed without changing my clothes after i went out.

- i can't stand screechy sounds like fingers scratching on blackboard, or the sssssssst sound when you write with a pencil.

- i don't like people yawning in front of me without covering their mouths.

- i don't like people coughing/sneezing in front of me without covering their mouths.

- i don't sit on public toilet bowls, i use tissue to wipe it first and then half-squat.

There's more.
What about yours?

I don't have time to upload my baby pictures.
