It's both regional and depends on how you are perceived.

I'm an introvert and I'm always surprised when a stranger talks to me, no matter where I am. But I make a point of always being pleasant back, no matter how I feel about it at the moment.

Sometimes it's just a couple sentences, and sometimes it's more of a conversation. It'd probably be more if I was better at conversations.

The only exception is if I feel the other person wants something from me, or they seem crazy or dangerous. I don't engage with those types.
