chat_history: ['I just had to replace one of the window panes in my house.', 'How come? And was it a pain to replace it?', "I'm not sure what happened.  I had to have a guy come out to replace it, and couldn't meet him, so my wife had to.", 'I hope he did a good job!', "My said he did!  I had quite a bit of confidence in him, based on others' feedback."]

situation: I just had a window replaced.  My wife had to meet him since I was busy, so I trusted he would do a good job in my absence.
