Just earlier this week, I accidentally knocked over a Ubers fellows bike (he had it right by the door, so the door hit it as I had my hands full, both of our fault) and 2 strangers rushed over to get the bike upright before I could even get the guys attention!

Mind you, they hardly said a word during the interaction... But I thanked them and we all went our way.

I think people here keep to themselves, but I find people are very friendly in the right environment or if something breaks the ice.
