You might be older than me but you certainly don’t look it! It seems as though you were blessed with the good genes in the family, sis! Happy birthday!
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!
Happy birthday, my love! I know that you worry about getting older but there’s really no need, my dear.
Just think of it like this: you’re younger now than you will be next year. If you simply keep this in mind each year that your birthday comes around you’ll never truly get old!
