     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 advise me to study
in the capital instead. Then I'll be able to continue living in
them. How can I persuade them to accept the fact I have grown up?
    Best wishes.
Yours,
John
