history: When I got falsely accused of eating my roommate's ice cream last night, I was completely outraged! I don't even eat ice cream because I'm lactose intolerant, and she knows that! 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! Well_comma_ did you eat her ice cream? 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.
current: I wonder who actually ate it then.
next: She probably did, during one of those nights when she stumbles into the apartment at 3am, drunk, with some random guy she brought home from the club.
