I was tempted, in fact I had it typed, to say that I have a high tolerance for that sort of thing from living in the southern US and spending several years as a waitress. Around here, there's all kinds of "friendly", good bad and in-between kinds. And, of course, you get all kinds as a waitress.

Sometimes it's nice, it depends on what they're saying and what kind of mood you're in. I've heard very meaningful stories from people and will get little positive boosts sometimes while I'm out because strangers strike up innocent, warm conversations with me. I don't usually do it myself, but I like it when others do.

Sometimes it's creepy and/or people get attached to you. Men can get a little pushy under the guise of friendliness or people tell you way too personal and sometimes upsetting stuff. Health conditions are dangerous territory, that's rarely gonna be okay, and I can't imagine why someone would give a stranger their address.
