I'm saving nothing

You will be slaves in a castle.
For every kiss there will be a snicker.
For every bottle there will be a pupil.
We are free and can climb mountains,
But for every passport there is an entrance
And for every flake there is a drop.
Grains of former mosaics haunted us
And for every shred there was a sob
And for every sob there was a silence.
For all our freedom we had been chained,
But for every laugh there had been a caress;
But for every love there had been a smile.
