He said he'd call back, but he didn't, did he.
He's not gonna return your call. He's found someone else. But there's nothing to fret. Someone else might just come your way. And a smile can hide everything that's running through your mind, even if you want to kill the person who didn't return your call, just smile. No one has to know the truth.

Soon you'll find The rose that you've given him, trampled on the ground,
Just Like your heart,
Beaten and bruised
And then slowly everything that you've shared, every memory that you've kept within, all rewritten with one person in it. HIM.
And then the last straw of hair will be pulled, when he does the one thing that he said he stopped because of you.
That's when you figure out how much you meant to him.
Nothing.
Absolutely nothing.
And then you pull every string in your heart, tug every wire, shrug every moment asking yourself to just forget. Forget for one whole day and you'd be happy. But your mind and your heart unanimously tells you,
'You bloody idiot, you can't just forget.'
And a smile can hide everything.
No one needs to know the truth.

And then when he sees that you are struggling to forget,
 He's gonna walk up to you all proud,
And ask what's wrong with you,
Tell you that you are different now,
That everything that went wrong was your fault,
That everything that's happening to you is because you didn't listen to him,
And you'd want to say we were in this together,
And ask him if all the promises he had made were as broken as your heart,
But all you can do is smile.
Cause a smile can hide everything,
And No one needs to know the truth.

When everything is said and done, when you finally think its all over
The faint thought of "US" keeps running though your head like a broken tape player
That's when you see him
This time as a separate entity and not part of your life.
But if he was just as miserable as you were it wouldn't matter
But what mattered was that he had mastered the smile.
Cause a smile can hide everything, 
And no one needs to know the truth.
