Well, for one, you're not being anti-social.
Up here, well, it's pretty friendly. When I worked for a pharmacy I chit-chatted to A LOT of people

Sometime it was a chore but sometimes it was great.
During my first week at work a woman came in 5 minutes til close. Well, apparently she and her husband was having "communication" problems, well, we talked and chitchatted and I listened and gave her my advice. She had just gotten married and moved to a brand new city, so she was just feeling very lonely. After we talked she thanked me for "just listening" and she later left. A month later she came in to tell me thanks for her decison not to end her new marriage.
So, all in all, I like to talk to strangers, you never know what you may with them or visa versa
