My wife and I were newly married and I was trying to impress her with my technical expertise.
I was trying to repair our washing machine but was unable to determine where a loose wire belonged. After working at it for several minutes, I decided to consult the experts.
I took the wire along with all the details (model, serial number, etc.) of my machine to a local repair shop. I explained my situation to the technician, who looked at the wire for several minutes. He said he thought it looked familiar, but he couldn't tell me where it belonged either.
