chat_history: ['I was sad when my dog died', "I'm so sorry!  That can be a devastating time. I have been there before.  How long did you have your dog?", "I had him for 10 years. It's just so hard because he was my whole world"]
sys_response: I completely understand.  Something that helped me was to have pictures up and also have a little remembrance each year with some other family that loved him as much as I did.  Just take it a day at a time.
