It’s no wonder people mistake us for siblings rather than cousins because I too sometimes forget that you are my cousin as you’re so much more like a sister to me!
Happy birthday, my dear! I hope your special day is as special as you are to me!
I want you to know that I look up to you as if you were my elder sister, cousin. It has nothing to do with age, only the fact that you look so much older than me!
I wanted to get something extraordinary and particularly special for a cousin who is more like a sister to me, but then I realized something: You already have all of that in me!
I hope your birthday is as wonderful and as meaningful as you are to me, my dear! Wishing a very happy birthday to you!
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!
