How about looking before you sit? My wife has never complained about me leaving the seat up.
My personal pet peeve is that she doesn't seem to know how to put the cap back on the toothpaste! It's a small thing, but drives me nuts.
I made a deal with my wife: I'll put the seat down if she puts the cap back on the toothpaste. It's worked so far.
May as well let that one go. Life is too short to waste angst on toothpaste caps.
Get those pump bottles of toothpastes, then you won't have to worry any more about having to: 1. pick the tube up. 2. take off the lid 3. squeeze 4. put the lid back on
OR
Have all those pesky teeth extracted and then the fake ones can be left in the denture soaker box overnight. Also, as an added bonus, YOUR tube of denture toothpaste will be separate from HER tube of real toothpaste. . then, you can chuckle to yourself every time HER tube of real toothpaste dries up! Chortle! Snort! Hah!
