Gayle's parents were away - and they had asked her to check on their house while they were gone. Gayle's one of our ministry team. It was a pretty cold night - Gayle thought the heat should be on. She called her dad - in dad fashion, he said, "You should know what to do - done it before. Probably just a zone valve is stuck." So Gayle went to work on the zone valve - she really went to work on it. We're talking about desperate measures - like beating the valve to death with a screwdriver and actually breaking blood vessels in her hand in the process. It refused to stay open in spite of Gayle's vigorous encouragement. Valve 1, Woman 0. When dad got home a few days later, he went to work on it - and it was very easily fixed. Of course, he worked on the other valve - the right valve. Gayle had been working on the valve, it turns out, that was already working! He told Gayle she had made a simple mistake - she put a lot of effort into fixing what was already working - and no effort into what really needed the attention.
