chat_history: ['So the other day was my 23rd Birthday! I had no idea what my friends had planned but i walked into a room, a room which i thought was empty as the lights were all off, and all my friends jumped out and yelled happy birthday! It was such a shock, and felt so nice to have people who cared deeply about me provide me with such an experience!']
sys_response: Must of been pretty surprised, Also great to have friends like that.
situation: A situation in which friends organize a birthday party for you when you did not expect them to do so. You walk in a dark room, turn on the light and all your friends jump out and say happy birthday and present you a cake.
