SISTER: Now what do you want to talk about?
YOU: You don't know? What about your favourite "personal assistent"?
SISTER: What do you mean? This is just my thing and it's nothing to talk about.
YOU: Oh really? What would our mother thought about her sweet little doughter that never drinks, don't go clubbing and gets the best grades at school for "free"?
SISTER: You wouldn't you little pervert! She wouldn't give me any pocket money for weeks!
YOU: Thats right so what should we do with this little problem hmm??
