person A: I saw a man slap his dog on the sidewalk a few times while I was on the bus.
person B: Holy cow! Did you call him in?
person A: I should have_comma_ but last time my girlfriend did that the police ignored it. I was so angry.
person B: Oh man!  Do you have a dog?
person A: I do_comma_ and I couldn't fathom how someone could do that. I wanted to hop off the bus and yell at the guy.
