person A: Hi_comma_ I went to a park and I set on a bench. I didn't notice that my wallet felt. A man came to me from behind giving me back my wallet.
person B: Thats a sweet man_comma_ I hope you acknowledged his kind gesture. 
person A: Yes_comma_ I did. I was so grateful because I have a lot of money in my wallet.
person B: Their aren't that many well rounded people in the world these days so when you see one you should always show appreciation!
