It is amazing the number of years we have known each other.
Why have we put up with each other for so long? Do you think it’s because we like each other? Nope, it’s quite simple, we just know too many of each other’s secrets.
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!
I would tell you not to grow up too quickly and simply cherish the years, but you seem to be doing a pretty good job of that all by yourself, my dear sister!
I’m wishing you a very happy birthday and sending a big kiss!
You’re another year older and more beautiful than ever, little sister! Happy birthday to you!
Just a word of wisdom from your dear elder sister, keep hold of your beauty and cherish it for as long as you can because once you get to my age those good looks won’t stay around for long!
Happy birthday to a family member I’d actually choose to be around even if we weren’t related!
It’s true that you don’t get to pick your family, but even if you weren’t the close sister-like cousin to me that you are you’d still be my best friend!
I know you better than most seeing how I watched you grow up, so my birthday gift to you this year is that I’ll continue to keep all the things I know about you to myself and not reveal any of your secrets!
