> a lesson learned

It's certainly a perspective of many, but many others think it's wrong, that children should run freely (there's a whole movement around that), etc.

IME from a life spent in cities has taught me that people - strangers, unhoused people, etc. - are great. Most will be happy to to help, have a pleasant conversation, etc. (Read Jane Jacobs who, iirc, examines it in detail.) Humans are social creatures - we don't live alone, we're made to socialize and live in groups.

You need to be a social creature too and read people a little. Obviously some people aren't in a mood to interact; don't be rude or an idiot (they'll probably ignore you). And there's risk to everything - you can die in an accident but still travel by car; you can catch diseases but you still leave your home.

Really, the exception I think I see at a higher rate is apparently wealthy people. Maybe they aren't accustomed to the need to help each other, but there seems to be a culture of anger toward those who might need some help today. Why don't they just support themselves like I do?
