Happy birthday to my younger sister who a lot of people think is actually my elder sister!

I’m sure it’s only because you’re so wise and mature that people think you’re older than me anyway, sis! Either that or I just seem super young and immature!

You irritate or annoy me
My beloved small sister,
You will always be!

Happy birthday!
Happy birthday to my baby sister who sometimes is so annoying that I wish she was far away, but deep down I know I would miss her after just one day!

Happy birthday from your elder brother!
Months and years have gone by
So fast. In the blink of an eye
You became a grown woman
and my personal heroine.

Little sister of mine,
You are so kind.
Always giving and giving
And taking nothing in return.

You love with a full heart,
But that’s not the best part.
You encourage others to love too,
No matter what or who.

Lessons learnt I must say.
So I’ve chosen this way
To show how I love you
And admire you too.

Have a birthday filled with love!
You were always such a free spirit and you never liked being told what to do. No matter what others said, you always chose to do things your way. This is but a reflection of your big personality and strong character.

I admire you for being like that. Never change!

Have the most amazing birthday and lots of love, little sis!
Sure, you’re getting older, but you’ll always be my annoying little sis! And to be totally honest, I wouldn’t have it any other way!

Happy birthday!
Happy birthday, little sis!

I don’t wish to take the spotlight off you on your special day today, but you should know that I already have the greatest gift ever.

That’s because simply having a small sister like you is the best gift I could wish for!
Little sister, you’re getting older each
year but that doesn’t necessarily mean
you’re growing up!

I hope you always stay the funny and
cheeky little girl I know and love, and
who growing up with was a total blast!

Happy birthday to you today!
