I will admit that I'm one of those people that tries to avoid talking to strangers. When a stranger talks to me, I try to be polite but prefer if things don't evolve into a conversation.

It's weird because I don't remember being like this as a kid...almost as if society has changed and being friendly and kind to others can be seen as "awkward", "weird", or "trying too hard". If that's naturally how you are though, don't stifle yourself. We need more kind people in this world!
