Dear uncle Ryan, 

How have you been lately ? I had a wonderful birthday party with my friends and family last week. I also received a lot of presents, including yours. I really appreciate the fact that although you were being away on business, you still remembered my birthday and sent me a gift. Thank you so much for your present as well as your kindness. When I opened your gift, I was very surprised and happy BECAUSE YOUR PRESENT WAS THE VERY THING THAT I HAD WISHED FOR . WHAT a lovely and beautiful alarm clock it was AND I liked it so much . Frankly speaking, it was one of the best presents that I had ever been given. I really miss you a lot now, so please come and visit me AS SOON AS you have come back home. I'm looking forward to hearing from you. 

Yours sincerely, 

John
