I’m American and was living in London when 9/11 happened, and I was overwhelmed and touched by how kind everyone was. Complete strangers would hear my accent in the shops or on the street and would stop me and say how sorry they were about what had happened. (And having strangers spontaneously start a conversation was not common in my experience). It was a very weird and isolating time, but I’ve never forgotten the simple things those English strangers did that made me feel a little less alone.
