They realized

She looked at her fingers
And he did too
Everything was normal
The match they made was pure

The past was long gone
And the broken parts were glued
With the innocence of love
And the hate they subdued

THAT'S LUCK
THAT'S WHAT IT'S ALL ABOUT
THAT WAS THE MOMENT THEY REALIZED

Nothing could change their feelings
For there was no reason to
And their related silence
Might convince you too

So if one day the question raises
What that feeling is that you got
Just consider that maybe luck
Means more than a lot

THAT'S LUCK
THAT'S WHAT IT'S ALL ABOUT
THAT WAS THE MOMENT THEY REALIZED
