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!
As time passes by and especially after all these years, I feel more and more grateful to have a buddy like you who is not only the best friend ever but also someone who is more like a brother to me.
