I had a girlfriend who would slam the fuck out of the toilet lid every time she used it. Not like, extra force, as far as i could tell, just let it drop from vertical to close. Super loud. It was ruining the hinges… I asked her over and over to please stop doing that. No change… I was set to install cork bumpers and she insisted NO, can’t do that. Okay… so stop slamming it? A year later, still every single time.
