Some people don`t understand that different persons socialize in different ways.
Some may bond over small talk, but not everyone is that way. Other may bond over humor, common interests, or many other ways, but there is that weird notion that talking a lot or being an extrovert makes someone a social person.
I met really sociable introverts that don`t neccesarily talk a lot, but they know how to connect with others.
Also, is impossible to click with everyone and it isnt neccesarilly out of hostility, so a polite distance with some people is okay.
