Thank you for relaying your story! That sounds like a really neat and valuable conversation. These days people don't reach out so much in the same ways they used to. There was no other way but to talk to strangers.
Your story made me think of a friend I've someone recently met, by this I mean several months ago, via Facebook. (Don't knock it just yet, it comes to bear). I "liked" a picture of hers and asked her a question about her cats, and we became "friends" on there to discuss the answer and the topic. But it's developed into buddies in a way, as she hails from Florida, and I grew up there, so there is some mutual teasing about the weather. Just friend stuff, and this transpired because a question was asked.
Back time up to about 1993, and you'll find me on my one-line BBS, calling other BBSs, meeting people locally that way, over the computer. I don't really know a lot of people I haven't met over the computer or through my airsoft hobby. What does that mean? I am not sure, but maybe the evolution of how people interact is becoming so different that a random encounter on the phone is a delightful break from the regimented way that people interact otherwise: online a good portion of the time.
This is one big reason why I turn off my computer at work and go visit other in their cubes and offices. If I ever receive such a nice, random phone call, I will enjoy it as well.
