Sisters can be annoying barnacles, but deep down you know you would have been lost without her. As a child, your sister was your best playmate, always nearby with a joke or a game. She was the person you relied on during family gatherings and local social gatherings. Your sister did her best to make you feel better when you were sick, helped you hide things from your parents, swapped clothes with you, and shared her books.

With her by your side, you took on adventure after adventure, and your journey isn’t complete. There are years ahead of you, full of shenanigans, smiles, heartbreak, drama, long phone calls, and childish giggles. The world would feel wrong without your sister, and there is no better time to let her know how much she means to you than her birthday.

This year, send your sister a happy birthday message filled with hope and adventure. A message with a image that encompasses your entire past and all that the future holds for the two of you together.
