all at once

It's not so easy
When you're hanging onto
Every word that people say
And you don't seem to think so much
Of anyone that tries to help
Everyone just grows so cold
Everyone just grows so old
All at once
I realizeThey knock me down
But I won't fall over
I can see them
They're up in the sky
I'm just as glad
To ask them why
And yet it doesn't seem to be
So long ago that you were there
Being told what you could do
Being told where you could go
All at once
I realizeThey knock me down
But I won't fall over
