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!', 'wow  thats nostalgic!!. It must have brought back lot of good memories', 'Yes, playing the machine we built together reminded me of all the good times we used to have.']
sys_response: does the machine is in good condition now?
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.
