I cant say clearly in short. I just mean even with US robbers, I as I met one, he is very kind as im kind and polite to him. We talked and shared our life story. I mean I can trust him. Not in vietnam, you cant trust all everybody
I agree most people here are pretty friendly, didn’t feel people were as friendly in Europe and Asia but also could be I don’t speak the languages where I visited
I guess the thing in US america, is like Jesus, you treat others as other treats you. I guess. I been in US, all people are nice, especially if you are nice to them they will like you.
