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