I'm bored

And the hardest part
Was letting go, not taking part
You really broke my heart

And I tried to sing
But I couldn’t think of anything
And that was the hardest part

I could feel it go down
Bittersweet, I could taste in my mouth
Silver lining the cloud
Oh and I
I wish that I could work it out

the hardest part
X & Y
coldplay

ps: and isn't the video bizarre? and how come they look soo young?
