She won't get off the phone
She won't leave me alone
When I'm talking to that guy
She can be a real nightmare
Gets me to do her hair
And says it never turns out right
But when I put on a face
She can tell
Cause she knows me so well

Closer than my closest friend
Someone who will be there til the end
My sister, sister
Deeper than the deepest sea
No-one loves you like your family
My sister, sister

She reads my diary
She borrows clothes from me
And I never get them back again
And she
And she locks the bathroom door
Says "Five minutes more"
And an hour later I'm still not in
And sometimes we fight
Every family does (oh yeah)
But that can't change our love

Closer than my closest friend
Someone who will be there til the end (oh, yeah)
My sister (my) sister (my sister)
Deeper than the deepest sea (oh, deeper)
No-one loves you like your family (ooh)
My (my) sister (sister) sister

To celebrate the good times
To help me through the hard times
To bring me down to earth
Remind me what's important
And who comes first
And who comes first
Gotta tell you who I'm talking bout
My sister, sister (oh, yeah)
And who comes first
Ain't no doubt about it
Who I'm talking bout
My sister, sister

She watches out for me
I know she'll always be by my side
By my side (by my side) by my side

Closer than my closest friend (oh, yeah)
Someone who will be there (ooh) til the end
(I know you're gonna be there)
My sister, sister (I know it)
Deeper than the deepest sea (so much deeper)
No-one loves you like your family (my perfect family)
My sister, sister (my sister)

Closer than my closest friend (oh, closer)
Someone who will be there til the end (oh)
My sister (my) sister (my sister)
Deeper than (my…) the deepest sea
No-one loves you like your family
My sister, sister
