I am fed up with my sister. My mum and dad treat her like an adult and they treat me like a child. She's only two years older then me. But she can do wath she wants. She never helps at home andI have to help with coocing,washing-up and cleaning. It's not fair. My sister and I both go to the same school. I usually get better results than her and she never does her homevork. She's got a boyfriend who rides a motorbike. She mustn't go in but I've seen her in town with hin on the motorbike/ I'm more responsible then she is but I can't have a boyfriend. I'm so unhappy. What can I do? Please help me.
