Is it to much for me to ask?

for my sisters boyfriend to not be over so much .. the back story is hes moving in in 3 weeks because there trying to save money to buy a house and hes on strike with boeing so i said he can move in but then i asked my sister that he not be over every night until he moves in because i would like a little quite because they are two of the loudest people i know.( i always have to turn my tv up because i can hear them threw the walls having ) and i enjoy myspace . its not that i dont like him or anything its just not the biggest place to have alot of people in and i just wanted to enjoy my apt for a few more weeks i mean i pay for it too so am i wrong for asking. my mom says i dont understand because i dont have a boyfriend and im just being mean to be mean i just feel that im not really being respected what do you think
