The Hardest Part by Coldplay

...
And the hardest part
Was letting go not taking part
Was the hardest part

And the strangest thing
Was waiting for that bell to ring
It was the strangest start
I could feel it go down
Bittersweet I could taste in my mouth
Silver lining the clouds
(Oh) And I
I wish that I could work it out

And the hardest part
Was letting go not taking part
You really broke my heart (oh)
And I tried to sing
But I couldn't think (couldn't think) of anything
That was the hardest part (oh, oh)
I could feel it go down
You left the sweetest taste in my mouth
Silver lining the cloud
(Oh) And I
(Oh) And I
I wonder what it's all about

I wonder what it's all about

Everything I know is wrong
Everything I do it just comes undone
And everything is torn apart
(Oh) And that's the hardest part
That's the hardest part
Yeah, that's the hardest part
That's the hardest part
