Happy birthday, my dear! 

Here’s to the many years of laughter and 
creating wonderful memories together 
that are still waiting to be written!
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!
Don’t worry about getting older, my
dear cousin!

It happens to us all but luckily for us,
we have great genes that should see
us age more gracefully than others!
How fortunate are we!

I hope you have a birthday that’s as
beautiful and fabulous as you are!
Wishing a very happy birthday to my
favourite cousin today!

You’re like a little sister to me, and you
always remind me of myself when I was
your age! It’s wonderful to see that you
are such a happy kid, living an enjoyable
childhood just like I did!

I wish you many more happy years and
that your smile never fades! Sending
you lots of love and big hugs on your
special day, sweetie!
Happy birthday to my beautiful cousin, who will always be more like a sister to me!
Growing up together we were inseparable,
and even now years later it is no different!

We are closer than cousins, we are soul
sisters for sure! I hope that you have the
most incredible birthday today that you
deserve, my dear!

You mean so much to me and I just want
to see you happy in life!

A very happy birthday to you, sweetie!
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!
Happy birthday to you, my sweet cousin!

Seeing as it’s your special day, I’ll let you in on a little secret: I know your true age! Well, with us being as close as we are what else would you expect!
Happy birthday to my cousin who
funnily enough happens to have
the best cousin in the world!

How crazy is that!
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!
Happy birthday to you!

If I had to give just one reason why you’re more like a sister to me than a cousin, it would be that growing up together you would annoy me just as much as any sister would!
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!
