I prefer to have things in sets of 3 if possible and not inconvienent and my light switches all have to be even (we have some in the basement that have 2 switches and I'll go out of my way to have both facing up or down)Thank God! My huaband thinks I am wierd because I keep the volume on the car radio, and the tv. Lol. I will tell him I am not alone in the even number quest. Do you find y'all do other things in even numbers, or just volume? Sorry, I know its off chicken topics but, I jad to ask.
