Wouldn't you say thats unfair?

Basically im Mandy and im 12 (im suing my bigger sisters yahoo) isnt this unfair th fact that my mum wont let me be with my boyfriend but im in love with him and i dont want to leave him we do everything together and were hopping to get married and have kids and so other stuff that people on tv do and also she keeps nagging me to clean my room and wash teh dishes she should do it herself dont you think? im only 12
