Should one leave the toilet seat up or gingerly place it back on it's home? I say put that bad boy down, one of my simple life truths, taken from "Zen and the art of toilet seat etiquette". I find that many people mindlessly leave it up; I also find that many people are perplexed when I suggest otherwise. Toilet seat up at an open house? Not on my watch! I even put them down at open houses that I'm just visiting.
As Forrest Gump would say, "That's all I have to say about that".
