The song What Do They Know? is performed by Westlife .
All they know
Is when we fight
They never see us
In the lovin' times
What do they know?
They don't know a thing
And they don't know
How the laughter flies
Only the stories
Most of which are lies
What do they know?
They don't know a thing
How can you understand
A love so strong?
When you've never shared
That with someone?
And when all the lies
Are dead and gone
We'll still be here
We'll prove them wrong
'Cause they don't feel
Your touch at night
The way your hair falls
In the mornin' light
What do they know?
They don't know a thing
How can you understand
A love so strong?
When you've never shared
That with someone?
And when all the lies
Are dead and gone
We'll still be here
We'll prove them wrong
'Cause all they know
Is how to criticize
They'll never take a chance
In their own lives
What do they know?
They don't know a thing
And all I know
Is they don't know a thing
