I should write my own book. I remember my first rental house. I was in college, studying for an exam, when I got a call. The tenant didn't speak English very well, but he was excited and kept saying "fire." I rushed over to the house expecting to see fire trucks and flames, but all was quiet. It turned out, that the hot water heater did not work. I had to ignite the gas starter light.
