Coldplay - Harmless lyrics

If you call and call your self esteem is low
And I heard you'd called
Is there no calling? And away I go
Any way you go i was o­n your tail
As clear as crystal

But it was harmless it couldn't hurt you
Oh you were helpless
I know you'll get through i know, I

Chemicals are cold see you sit down o­n
A chemical you cause is like a crystal
So I heard you say i got to get away
I'm o­n a second trail as clear as crystal

But I was harmless it couldn't hurt you
Oh you were helpless
I know you'll get through
