I no how you fell, my mum and dad and little bro and little sis won't give me any privicy I spent over 30mins in the shower to get away from all of them because I want my privicy, I have tried the signs on the door but they still walk in I hate it and 1 time I did say to them when they did walk in ''just give me some F-ing privcy ffs!! '' and it worked :)
