What is the most annoying habit someone can have?

I could make a long list, but at the moment I'm going to have to go with asking questions and then talking over people when they're trying to answer.

Being a hypocrite about every damn little thing.

When someone would ask a question, when your giving the answer, they suddenly wont listen to what you are saying. What’s the point of asking?

constantly complaining about their life and doing nothing to change it.

bringing an airhorn and tooting it everytime some tries to speak

Making everything about themselves.

Yapping endlessly

Being untidy!!!

arrogance

Chewing loudly and snapping their gum

Blowing their nose when I am eating!! 🤢

being a twat

Being a cunt

When they are pushy and don't respect personal boundaries or lack that empathy that tells regular people to avoid a certain conversations etc.
