I'm not even a little bit surprised
I've always known she'd be the most beautiful bride
It makes me glad to see her walking to your side
To take your name, to be your wife
She's taught me everything I've ever known
And always been there every time I've been alone
So it feels strange to watch her find another home
But I have faith that you're the one
Yes I have faith that you're the one
And you'll take care of my big sister for life
You'll make her the happiest wife
Cause she's the most deserving girl
Of all the best things in the world
Take care of my big sister for life
Can't help the tears from flowing down my face
Because I know that things will never be the same
I'm more than happy for you, I'm just scared of change
Say things won't change
Say things won't change
And you'll take care of my big sister for life
You'll make her the happiest wife
Cause she's the most deserving girl
Of all the best things in the world
Take care of my big sister for life
I hope you know that you've struck gold
A diamond in your hands you hold
The most beautiful girl that's walked the earth
A beaming light that shines so bright
And a heart so big, not just a sight
You're such a lucky man to know this girl
Please bring her home once in a while
And never stop making her smile
I know that you've already made her world
And you'll take care of my big sister for life
You'll make her the happiest wife
Take care of my big sister for life
You'll make her the happiest wife
Cause she's the most deserving girl
Of all the best things in the world
Take care of my big sister for life
For life.
