Dear Uncle,

Hope you enjoyed my birthday party yesterday. I'm so glad that you joined in my birthday celebration.
I am writing this letter to thank you for giving me such a beautiful birthday present. I always wanted to have that kind of watch. You fulfilled one of my wishes uncle. I am very happy and I thank you a lot. 

It's not only a present for me rather it is a symbol of your love for me. Once again I thank you whole heartedly.

Yours lovingly,
(name)
