There are few things as comforting as being safe in the knowledge that a true, sister-like friend is only a phone call away. Happy birthday to you, my dear!
No matter how old we grow or how far apart from one another we may be, you will always be the most special sister to me. Happy birthday, dearest sister.
My dear sister, I’m wishing you the happiest of birthdays possible today. May you enjoy your special day to the fullest and cherish each day of this new year.
