Over the years you have driven me up the wall and tried my patience time and time again, but really I have you to thank for that as it’s partly down to you that I’m such a calm, patient, and zen person nowadays!
Happy birthday, sis! On your special day, I want you to know that no matter how old we get, the fact will always remain that you are my younger sister and I’ll always be there to look out for you.
You’re my little sis and I care about you and love you a lot! I hope you have a fabulous birthday today!
How is it that you’re my elder sister and even though you’re turning another year older today, you simply never seem to age?! You’re making me look bad, sis!
I hope that I too will follow in your footsteps and just stop ageing at a certain point as well!
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!
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!
