What exactly to do with the The Seat™ is a well-known minor point of contention among couples.

On one hand, it's just a toilet seat. It takes only a few seconds to move. And if you're single and use it while it's up most often, it might logistically make sense to leave it up instead of putting it down after.

On the other hand, half of the population never utilizes it while it's up, and everyone (hopefully) uses it while it's down at least some of the time. In theory, this means that it makes sense to keep it down by default since that's the orientation it'll be used most often in.

So what about you? Do you leave the seat up or put the seat down? And why?
