chat_history: ["No matter how many times I told her that I didn't do it, my roommate insisted that I ate her ice cream last night! Unbelievable!", 'Well, did you eat her ice cream?', "I certainly would have liked to, but I'm lactose intolerant! If I had eaten it, I would have been so miserable that there's no way she would've mistaken it.", 'I wonder who actually ate it then.', '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.']
sys_response: So are you saying it could be the guy?
situation: 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!
