Dear Dad.

Happy birthday to you !

On this special day I'd like to talk to you   a special way.

I don't think I'm good at      you my thoughts face to face. so I'm writing to you to express my love for you.

You're neither rich nor famous, but in my heart, you are one of the greatest       in the world. I'm       you. You have         been interested in fame and wealth (财富 ).  You always work hard to get your work      . The smile on your face shows you're pleased with the family. You take good care of my grandparents. You help me with my schoolwork and go shopping with Mom on Sundays.

In the past ,  I don't care        you were with me or not. Now I am sorry to say I        you my respect ( 尊重   ) before. But I am thankful for what you have done for me. I am quite lucky that I have        a good father. I am happy that now I can let you       how much I love you. You arc successful as a son, a husband. a father and a friend.

I hope you'll  be happy forever

Yours ,

David
