Why should i care?

I don't know where to start or when to stop
Another closing door, another ticking clock
People pass through like they're made of air
And i have to look twice to see who's there

I hope there comes a time when i really don't care
Why should i care?

Everybody's looking like they've got something to say
About the things i do, about me and you
It goes in one ear and out of the other
You don't know me sister, you don't own me brother

I hope there comes a time when i really don't care
Why should i care?

I don't know what he said
I don't know what she said
But now everyone i meet
When i walk down the street
Says off with her head

I don't know what he said
I don't know what she said
They're all off their heads
