If someone is so socially inept and surrounded by equally socially inept people who don’t call out this behavior, then it’s possible they don’t have anyone who is part of society at large that would inform them of how their actions will be perceived by most members of the public.

I’m not commenting because it hurts me in any way. I’m commenting because this person is going to have a relatively difficult life socially if they continue with the behavior they currently exhibit.
