chat_history: ['I have never been so shocked than when my husband threw me a birthday party without me knowing.', 'Was it fun?', 'It was so much fun. I thought is was going to be another normal day. Wake up, go to work, etc. but I was wrong about that!']
sys_response: Was it recently? Happy Birthday
situation: I could not believe for my 40th birthday, I came home from work that evening and the house was quiet. I walked in and the house was filled with people shouting Happy Birthday. That was quite a shock.
