Everything has to be "Real friendship" What does that even mean? You're just talking to others to be a decent human being. Not everyone has to be your wife/husband/BFF for ever.
I've seen plenty of people after commercial transactions. In fact, many times I remember people and they remember me for pleasant interactions - they aren't my best man but it's still really satisfying to me.
This is not a benefit of living in the suburbs. You can have a pleasant commercial transaction anywhere in the world - you pay for that.
It just goes back to the common theme these days - everything is something or someone else's fault. No one ever just says " man I'm feeling lonely, maybe I should join this club, or start going to this coffee shop and just strike up conversation."
No we have to "blame the suburbs" and "blame cars." No one wants to just take responsibility for themselves, they just want to complain about everything else causing their problems online.
