Dear Aleena,
I hope you are doing well. It is a wonderful day for you because this day you were born. I have just received your birthday card. Thank you very much for your invitation card to your birthday party. I am very happy to congratulate you on your birthday. I am blessed to have a great friend like you. I pray that you get all happiness and success in your life.
I am sorry that I cannot come to attend this function because of the illness of my mother. However, I have sent you a gift by post. I hope you will receive it today. May God protect you from all kinds of calamities. We will celebrate this day soon.
Pay my regards to my parents.
Yours affectionately,
X.Y.Z
