I’ve lived in the same apartment for over two years now and the dudes I live with have been there for roughly the same amount of time. Lets say things have got pretty comfortable around the place. When the boys have mates around to drink the bathroom becomes open domain as in no one closes the toilet door. It’s fairly sheltered but for the longest time the sound of other people peeing made me feel pretty grossed out. As time has gone on me and one of the boys just leave the door open because we pee heaps and closing the door becomes a hassle. Plus, we’re both home the most out of the three of us and it really does not bother us. Our other flat mate finds it pretty revolting but I think he forgets he totally does the same thing a few beers deep.
