Okay, my mum just divorced my dad but they have been separated for 7years...that was fine but now things have changed mum wants to divorce my dad and all of a sudden mum is now calling stuart (her boss that lives with us) babe, honey etc. and I think they are going to get married... I don't know! but that is not all of my problems this is the BIG ONE! my brother Malcom is getting all of the attention and like every 2 minutes there is laughter in the room from my aunty, her friend, my dad and my dads girlfriend...but NO when I finally say something I am ignored or it is so not funny and no one cares!!! so every night now I go into my room and her them laugh and scream at the t.v. cause they are always watching football which I personally HATE!!! Or when we are picking something for dinner. Malcom says "KFC?" AND I SAY "SUBWAY PLEASE?" and dad says okay then KFC! so yeah! and I tell my friends at school and they just don't understand or they try to make up a worse story than mine up in there head and i just get up and leave! so some one who cares...HELP!!!!!!!!!!!!!!!!!!!!!!!!!!!!…
