Write a letter to your uncle thanking him for a birthday gift

My dear Uncle,

I wish you had given me a nice birthday gift personally. All of us missed you badly. I am grateful to you for the fine birthday fit. It is indeed very kind of you to have remembered my birthday. The wrist watch that you have sent to me was in fact much needed by me. My examinations are approaching fast and I badly needed a watch to plan my studies. Rest assures, I shall make the best use of the birthday gift you have sent me. I shall work hard and try to get first division, the credit for which will go to you as well. Let me one again thank you for the birthday gift. Please pay my regards to dear aunt. I remain,

Yours affectionately
