It was a throw-away line you said.
But then again - it wasn't. At least - I
Wasn't sure.

So I picked it up when you weren't looking
And put it in my pocket. Later,
Carefully unfolding it I thought you
Might have wanted to say more.

But now, creased with time and wondering I see
It's just a scrap. So I put it back.

But carefully -

Upon the floor.
