the dog

Mum and I keep having this argument about me getting a dog. One minute she says yes, next a flat out no. The this that really pisses me off is that as soon as I start proving my point, she shuts up and refuses to talk to me because shes 'not in the mood'. The reason I ant a dog is so I have someone to talk to. I've always loved dogs and had them until I was about 13. I had a dog called Ricky and he was my best friend in a family where my mum constantly decides shes 'not in the mood' to make her kids dinner, tells us we're 'not her problem' on dads weekend and tells me I never appreciate anything and a sister who hates me, calls me stupid things like fat and frequently tells to 'go kill myself'.
I told mum that dad thought it was rediculous that she has be in the right mood to feed us and she said something like 'thats what you do, you don't get your own way so you say things just to hurt people. Felt like telling her to go and fuck her boyfriend unless she was cheating on him too.
Can't wait for year 10 to finish so I can live at dads and stop being treated like crap.
