Dear Miss Wang,                                    
    I am having some troubles                       
with my classmates at the moment. I'm geting     
along well with the boy in my class. We often     
do homework together or we enjoy helping        
each other. We have become real good friends.     
And other students have started gossiping. They   
say that this boy and I have fallen love. This    
has made me angrily. I don't want to end         
the friendship, but I hate the others           
gossiping. What should I do?                    
    I'm looking forward to receive your reply soon.                                             
Yours,                                               
Lisa
