Da** why are you so pressed about that sh**, and how the fu** is that gross??? Yeah you might be changing but a lot of siblings walk on that and never actually minds it, and maybe I do have only one fuc**** sibling, but my relationship with them as a sibling is pretty normal, even I have cousins who suddenly does that but doesn't even matter, you might be uncomfortable for that sh** but not all of us, if you think your sibling shouldn't do that and so do you, then that's you, a lot of people experience that with their own siblings, they have heard about privacy but they probably showered as when they were kids you never know, that's why she would just burst into the door nothing else, I'm not even trying to get into your business I'm just saying and then you got the whole lot pressed about that sh**.
