I dropped money on the ground in public.  A kind and honest stranger saw me drop it and returned the money to me.  I trusted that person after that.
I was in the park the other day and dropped some money on the ground without knowing it. A kind stranger witnessed this happen and picked up the money. That person then returned it to me.

That's so awesome. Isn't it so nice when people do nice things for each other in their communities?

Yes, it is nice when communities watch out for each other.
user
My community is great about that kind of thing. I'm glad you got your money back!
assistant
Yes I am glad too. I rewarded the person by giving them what I had dropped since they appeared to need it more than me.
user
Oh that's great! That's really nice of you.
