Yeah, I had a feeling that someone might good-naturedly rib me about this, esp the seat-down question. Just to clarify, I'm talking about the lid, not the seat. Like all of y'all, I like the seat down too. And I like having the lid down for when I need a substitute chair too. But when we work all day and the lid is down, I just feel as though I've noticed that the toilet seems to get smellier more quickly when it's down. But I just don't know if that's true or not. Likewise, I don't know if keeping the lid down really makes a difference in preventing evaporation, which I think is the green argument that my husband will make if I bring this up with him. - Paula.
