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!
People say that you get more beautiful with age, but surely they mean you become more beautiful on the inside because the cracks are certainly starting to show on the outside!
I’m just kidding with you, sis! I hope you have a wonderful birthday today!
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!
