I am up most days by 8am. Have two sisters staying with me, in their late forties, early fifties. They are here for 10 days, and are never up before 11am. I find it a bit annoying, as i dont expect them to be up at the same time as me as they are on their hols so to speak, but I think 11.30 is pushing it a bit, means that by the time they have showered and had breakfast it is about 12.30 which is about time i have lunch. It restricts what I can plan for us all to do as we only have the afternoon to work with. They also want to sit up till 12.30 or 2am when I am dying for my bed by 11pm. Should I/can I say anything without sounding unwelcoming?
