person A: No matter how many times I told her that I didn't do it_comma_ my roommate insisted that I ate her ice cream last night! Unbelievable!
person B: Well_comma_ did you eat her ice cream?
person A: I certainly would have liked to_comma_ but I'm lactose intolerant! If I had eaten it_comma_ I would have been so miserable that there's no way she would've mistaken it.
person B: I wonder who actually ate it then.
person A: She probably did_comma_ during one of those nights when she stumbles into the apartment at 3am_comma_ drunk_comma_ with some random guy she brought home from the club.
person B: So are you saying it could be the guy?
person A: Either he ate it_comma_ or she did and she just doesn't remember doing it. All I know is that I didn't do it_comma_ and I'm about to hulk out!
