Dear Mom,
    Mother's Day was coming. I'm sorry that I am abroad           
and can't send your flowers, so I'm writing to you.                
    Mom, I know I have never expressed my thank to you         
before. But on today, at this special time, I just want to tell          
you loudly: I love you, Mom! Thank you so much by not            
only giving me life, but also teach me how to be a good            
person. Thank you for all you had done for me. Mom, though       
I may often say it, I do love you. Nobody can take your          
part in my heart. Whenever I am, I will always love you.            
    Hope you good health and much happiness every day!        
                                  Your little girl,
                                   Jennifer
