person A: You will never guess what happened today! I am so embarrassed!!
person B: Oh no_comma_ what happened?
person A: I tripped over a man's foot and landed right on top of a very grumpy man who shoved me into another guy! 
person B: Oh wow! Where did all of this take place? Sounds like a rough part of town?!
person A: No_comma_ it actually happened at the subway_comma_ I guess the man was in a rush for work so he shoved me out of his way when I tripped.
