chat_history: ['I went to a bar I used to go to in college, and I was surprised to see an arcade machine I built with a dear friend of mine!']
sys_response: wow  thats nostalgic!!. It must have brought back lot of good memories
situation: A decade or so I designed an arcade machine for some friends of mine that owned a bar. They no longer own it, but I went back recently and our machine was still running. Playing it made me miss my buddy and all the good times we used to have.
