person A: I witnessed a man rob an old woman walking across the street. Boils my friggin' blood!
person B: Oh my God that's terrible!  So sad.  I'd be mad too.  What did you do?
person A: I would have chased that punk down if I was close enough_comma_ but I saw it from a distance. 
person B: Did the police come? I hope she got her stuff back
person A: They did_comma_ and I explained in as much detail as I could remember what he looked like. Hopefully they catch him.
person B: No kidding.  I would hate for that to happen to anyone else.
person A: I felt so bad for her. She seemed really shook up.
person B: I bet.  The world can be so scary!  I'm glad she was okay
