Dear Abby，

    How are you? Today I've got a wonderful news to tell you. I have offered a scholarship at a university in Australia for my further education. One hundred and twenty students took exam for it, but only a few was chosen and I was one of them. However, my parents are not happy about it. They are strong against me going there. They say it is too far away that they will not see me for a whole year and they are afraid of I will feel lonely. They can't imagine a girl so young live alone. They ask me study in the capital instead. Then I'll be able to continue living with them. How can I persuade them to accept the fact I have grown up？

Best wishes,

Jane
