Hope this letter finds you in good health dear. We all are doing well here.
First of all, wishing you a very happy birthday. May God bless you abundantly and may you always be as amazing as you are now. I wrote this letter specially to wish you all the happiness in the world. I still remember the day when I first held you in my arms and you were crying. And all those days, when you had won every possible challenge. Not everyone is as brave as you.
Always remember, that I will always be with you. Whatever decision you do in life, I will make sure that I am on your side. I promise to fulfill and take care of all your happiness. I will always keep you in my prayers and make sure that you stay strong and healthy.
Just take care of yourself and write back to us. When you will be back, we all will celebrate this happiness together. I will be eagerly waiting for your letter.
With lots of love,
