Sometimes people can't tell us apart
I know what you're gonna say before you start
Look in the mirror, you'll see my smile
Pick up the phone and melt away the miles
I know you'd do anything for me
Climb any mountain, cross the deep blue sea
'Cause it's only water, it's not thicker than blood
When I need you, you roll in like a flood

CHORUS: You're my sister, you're my best friend
We've got a love that'll never end
Pure as gold, rare as a gem
If you weren't my sister
I'd choose you for my friend

Even though you're far away we're still so close
Our bond's so deep that it's in our bones
Stronger than diamonds, solid as stone
It lives in my heart and sings in my soul

CHORUS: You're my sister, you're my best friend
We've got a love that'll never end
We're closer now than we've ever been
If you weren't my sister
I'd choose you for my friend
Ooohh, my best friend
You know you are my best friend
