Mom doesn't want to give me the big room
OK I'm 14 and live with my mom and dad and brother and sister. The problem is that I want the big room that my brother and sisster have been sharing. The thing is that my mom says no. she's going to give it to my little sister that's like 7 and I told her I'm going to be leaving this house sooner than her so she can have it all to herself when I leave, but she says no. I don't know why. All I know is that I want the big room so badely. And I don't want my sister having it cause first of she's too small and like I'm bigger so it looks weird. My mom always wants me to be mature. I don't know what to do to convince her she seems very determined. ANY IDEAS HELP!.
I'm female and yes I have my own room now
