not sure what you meant by "asocial" so apologies if I'm repeating, but also less accustomed to being around other people, putting up with their foibles, and not having complete control over your environment.
As a car-free person I spend a lot of time in the same space as people I probably wouldn't socialise with, and who I don't necessarily find pleasant to be around.
But you rapidly learn to live and let live. You're all stuck on the same damned bus.
