The Audacity
We’d definitely say that people who try to approach us have some audacity. Especially when it’s strangers who are trying to approach you, people you dislike, or people you’ve made no eye contact with. Basically, anyone who isn’t a part of your close inner circle should never, under any circumstances, try to approach us.

If they do, the first thing we notice is definitely their audacity. How dare they speak to us? Can’t they see we have absolutely no interest in interacting with our environment? Can’t they tell we’re introverts who just want to be left alone? We have no interest in speaking to anyone, certainly not people who approach us from out of the blue.
