I totaly agree, I have met some who do not know how to change a light bulb because they did not know which way to turn it. Another one stayed in a new cottage and stayed there two weeks before telling the landlord he had no hot water in the shower, he had it in the kitchen and bathroom sink but not in the shower, upon examination the hot and cold pipes were in the wrong place so when he turned on the hot only cold came out. Duh would not the ordinary person just try the other tap first. I have met some real winners in my life time.
