I have told my wife I will either put the seat up or I will put it down, but not both in the same trip.....that's when the fight started!
In my early years we fight a lot me and my now ex-wife over this.. I might get beaten here on that! But i realized, over many years, that peeing while standing up, isn't really approriate, since it create somekind of a mist all over the bowl, and spray the nearby cabinets and side walls. To make it simple it is not clean and also disgreably noisy.. So i learn to sit down! But heck i lift and let the seat up once in a while just to heck of it!
