My dear big sister, how is it that with each birthday you get another year older, yet you never seem to age a day! I hope that trait runs in our genes!
I’m wishing you an amazing and beautiful birthday today, sis!
Today, I’m wishing a very happy birthday to my sister who has everything she could ever wish for, including a wonderful sister like me, most importantly of all!
Enjoy your special day, sis! I hope that it’s as special as I am!
If things tend to get better with age, you must be getting pretty close to magnificent now! Your age is merely the number of years that the world has been enjoying the wonderful person that you are!
When you close your eyes and blow out the candles on your birthday cake today, sis, I know you’ll be wishing for one thing and one thing only: to be younger!
How do I know this? Because it’s what we all wish for, of course!
Happy birthday to my younger sister who a lot of people think is actually my elder sister!
I’m sure it’s only because you’re so wise and mature that people think you’re older than me anyway, sis! Either that or I just seem super young and immature!
