Diamonds in the sand

By the way, I don't easily forget
What you said by the seaside at sunset
By the way, I will not necessarily ask you to stay
Though that should be an easy task

Am I dreaming? Am I breathing?
Am I losing diamonds in the sand?

By the way, I don't usually regret
But today, I lost before I placed my bet
By the way, I don't exactly know what to say
I want back the stone that I just threw away

Am I dreaming? Am I breathing?
Am I losing diamonds in the sand?

When it's larger than you ever calculated
When it lasts a little longer than you ever estimated
