Both of them sitting at the piano
The place is closing and he says to her:
You know, it's great how well we got along.
She replies, with a bit of nostalgia:
Yes, we did have our moments.
He plays her a tune on the piano
She playfully pushes her shoulder against his, asking:
Are you coming back?
He shakes his head, telling her:
I don't belong here anymore.
He closes the piano top and she sees her name written on it
You gave me a reason to play.
She remains seated as he goes away
Both of them realizing:
You never know what you do for someone
Until it's done
