chat_history: ['My wife and I have tried to have a baby for over three years, and had given up hope.  Two weeks ago, we found out she was pregnant.', 'I am so happy for you! Congrats!', 'Thank you!  We were both pretty shocked by the news, lol.']
sys_response: I wish you nothing but the best!
situation: I found out two weeks ago that I am going to be a father.  It came as quite the shock, because we have been unable to conceive for the last 3 years.  I'm stoked.
