Happy Birthday Sister Letter

My dear loving sister [mention the name of your sister]

A very Happy Birthday. May this day be filled with all the happiness and enjoyment you seek. Do you still dance around the house like a young girl, as you used to do on your birthdays? Do you remember our birthdays as kids?

What fun we used to have then. Remember those midnight birthday surprises? I miss them badly. Now that we both are in two different cities, I miss all those memories. 

As kids, our birthdays used to be so fun-filled. We had the custom to go to the church in the morning then, followed by a visit to the circus or the zoo or the theatre, and later eating out at the restaurant. You were always eager for the ice cream and waited for it till the end. 

Those days it was so exciting to unwrap our gifts. Do you still feel the same excitement while unwrapping the gifts? I still do. I miss those days so very much. I just wish we were together once again and can have all the fun and enjoyment that we used to have. 

On this birthday, I wish that may all your dreams come true. May you achieve all the success you seek for. May the almighty bless you in abundance. Just as I wish to tell you repeatedly that I love you so very much. The love and care you showered on me all these years is something that I can never forget. 

Now that you are busy building up your career, I know that you will achieve success in all the arenas.  

A Happy Birthday to you once again.

With love and hug,

Your loving [brother/sister]
