To you your sister is like an angel, someone who not only makes life beautiful for you but who have been forever there for you. She guides you like a mentor and fills your life with happiness and loads of cheer. You can sure not repay her back for all the love that she showers on you, but you can definitely let her know how much you adore her for every little thing she does for you. Send her this warm birthday greeting and just let her feel special.

To me you are like an angel from heaven above,
who have been forever there for me,
guiding my way like a mentor and a guide.
Wishing you loads of happiness and smiles dear sister
On this very special day.
