I bring this subject after what Lucretia told (in the remains of the day thread) that happened to her; a car hit her, the driver just continued his way and nobody cared to go see if she was ok. That brought me questions about how people behave together with strangers, people in their community, tourists, ect.
How are the strangers behaving with each others in your countries & the places you lived in or visited? Is it common to greet pure strangers, chat a bit on general subjects with them, ask people for the time it is or any other information one can seek for?
How is the community dynamic where you live & in the places you know at the neighbourghood, area, city levels? Is it really very different depending on wether you live in a rural or urban area, or in a different country?
