Happy birthday, cousin!

On your special day this year, I just wanted to tell you how much you mean to me.

There are few things in life as special as family, and you’re doubly blessed to have someone as spectacular as me in yours! Happy birthday, cuz!
Happy birthday to one of my dearest relatives! You might only be my cousin but to me, you will always be much more like an annoying younger sister!
Happiest of birthdays to you, cousin!

Seeing as you’re just as close to me as
a sister, I feel I can be honest with you
about anything.

So, I’ll just come right out and tell you…
I totally forgot to get you a gift this year!
If I didn’t know any better I’d never guess it was your birthday today as you don’t look a day older, let alone a year! Happy birthday, my beautiful cousin!
Laughing at each other or laughing
together, you’ll always be the person
I’ll most enjoy sharing life’s funniest
moments with!

Happy birthday, my sweet cousin!
Wishing my sister at heart the
happiest birthday possible today!

Love you, my dearest cousin!
We must be related because you have so
much style and sophistication just like me!

If people didn’t know any better or that
we’re cousins, they would definitely think
that we’re sisters!

Happy birthday, my dear! I hope you enjoy
your special day today!
When two cousins are as close and as inseparable as we are, you might as well just call them siblings!

Happy birthday, my dear!
Happy birthday to a cousin who doesn’t
get older, she simply gets more fabulous!

According to my calculations, by the time
you’re an old woman you’re going to be
truly spectacular!

I’m sending you all my love and big kisses
on your special day today!
Happy birthday! Your birthday is always a
pleasing time for me as it reminds me that
you’ll always be older than me, cousin!
Sometimes I wish you were my sister
But then I worry we might fight
So to have you as a cousin
Seems to be just right!

Happy birthday to you!
Wow, another birthday already, cousin?
With all these years behind you now,
perhaps you’ll finally start to grow up soon!

I’m just kidding with you! I wouldn’t change
your fun and playful personality for the
world! Happy birthday to you!
I’m still not totally convinced that we’re
cousins... I’m sure we are actually sisters
and there was just a mix-up at birth!

Happy birthday, sis!
You are more than a cousin to me, you’re more like a sister. Mainly because you dedicated your childhood to irritating me!

Happy birthday, cuz!
