This is in light of my IL's visiting and my FIL's inability to remember to put the toilet seat back down, as well as the lid. Every time they come over, and FIL uses the bathroom, he never does it. Granted, he doesn't do it at his home (and MIL puts up with it), but Tim puts both down because: 1. Nathan used to like to play in the water (when he was just starting to walk) so we had to make sure both were down to prevent him from playing in it. 2. We have a cabinet & shelf right above/behind the toilet. This poses a hazard for stuff to fall into the toilet if the lid is up. Personally I think it is very rude and inconsiderate to do this at someone else's home. Every time he is here, I have to go in and put the seat down after him. It's a minor thing, but still...it rubs my fur the wrong way with his rudeness.
