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 advise me to study    
in the capital instead. Then I’ll be able to continue living without    
them. How can I persuade them to accept the fact I have grown up?     
     Best wishes.                                                                                                
Yours,
