Roommate issues

Why can’t you keep your shoes in your bedroom, whether in the closet or somewhere else in the room? It seems like your previous roommates were more like you or just didn’t really mind some things, but obviously that is not the case with your new roommates. If you just forget and leave something out they should be a little more understanding, but I don’t understand the deal with purposefully leaving your shoes outside your bedroom and they obviously don’t either.
