Dear Abby,

     How are you? I've got a wonderful news to tell you. I have offered a scholarship

at a university in Australia for my further education. Three hundreds and twenty

students took the exam for it, but only a few were chosen and I was one of them.

Therefore, my parents are not happy about it. They are strong against my going there.

They say it is too far that they will not see me for a whole year and they are afraid that

I will feel lonely and will not be used to the climate here. They can't imagine a young

girl like me live alone. They advise me to study in the capital instead. Then I'll be able

to continue living with them. How could I persuade them to accept the fact I have grown up?
