It comes and it goes - Dido

Some days I wanna and some days I don't
Sometimes I can feel it and suddenly it's gone
Some days I can tell you the truth and some days I just don't
Only a change of mood, sun goes down
Someone says something too quick or too soon
A touch not made, one made too late
Army's of words cannot hope to contain

Then it comes and it goes
And I have no control

Some days I can think clear and some days I won't
Sometimes I can feel it and suddenly it's gone
Some days I’m strong and some days my skins broken and thin
That's when it feels and it takes what it needs
And it leaves before I get to know
Its only a step away, moments that
Army's of words cannot hope to contain

Then it comes and it goes
And I can't make it home
And there’s nothing at home
And it breaks me when it goes

Some days I wanna and some days I don't
Sometimes I can feel it and suddenly its gone
Some days I can tell you the truth and some days I just don't
Only a change of mood, dream comes out
Someone tells something too quick or too soon
A move not made, one made too late
Army's of words cannot hope to contain

Then it comes and it goes
And I can’t seem to hope
And there’s nothing at home
And it breaks me when it goes
