OMG! Nosy Parents PISS me right OFF

So, my problem today is nosy parents. Yep I have 2 of those, but only 1 who opens my mail. I get it. I am known for keeping secrets in my house, but in my defence, if I don't tell you about my mail its cos it doesn't concern you. And my new phone contract certainly doesn't concern you MOTHER! Jheez so judgemental. Its my damn decision if I wanna be paying £37/month, even though with a 30% discount I'm actually gonna be paying £29. Bottom line; don't try to tell me what to do, might be a reflex thing, but I'm only gonna go and do the total opposite. Also I can afford it, so leave me in peace Mother. I've been paying for my phone for the last 5+ why's she tryna get involved now?!
