Happy Birthday to my Sister
What’s the most popular two-word expression in the English language? Yep, it’s got to be “Happy birthday.” If you’re convinced a birthday greeting requires those two words in order to pass muster, here are some possibilities for you:

.>As your sister, I’d like to wish you a happy birthday. As your best friend, I’d like to spend it with you.

Birthday Greetings for Departed Sisters in Heaven
Perhaps those who best understand what a sister means are those who have lost one to illness or injury. The hardest feelings to put into words may be the ones that relate to loved ones who have passed on. One of the following birthday messages might strike a responsive chord and help you see more clearly what’s in your heart:
.>So many birthdays we celebrated together. So many cakes, so many candles, so many wishes. But today I light one more candle for you. And while it still burns, I make this wish: That somehow, somewhere, in some way, we are reunited, so that I will be able to re-experience the pleasure of your company, this time for all eternity.
.>Over and over, I ask, “Why was your life cut short?” But as I remember your smiles, your giggles, the sunshine that emanated from you, it becomes clear that you live on. The quality of your life — the quality you brought to my life — created an indelible impression that keeps you very much alive, today, tomorrow, and forever.
.>Your birthday is coming around, but you won’t be. That makes it hard for me — hard to get out of bed, hard to do my daily tasks, hard to smile. Until I start to think about what you’d say if you were here: “Shape up.” “Suck it up.” Get over it.” And that keeps me going. You keep me going. Thanks, sis.
.>Sometimes we fought. Sometimes I hated you. I kind of hate you now. How could you go away like this? How could you leave without ever coming back? And, how could you duck out before I was mature enough to tell you that you were my idol, my best friend, the most important person in my life?
.>A sister you truly loved never dies. She simply moves into a warm and secluded section of your soul. And on her birthday, that’s where you go to spend some quality time together.
