I wrote I love you

I wrote on a piece of paper I love you, I love you! I love you!... I wrote on the palm of my hand I love you, I love you! I love you!... I wrote on the walls of my house I love you, I love you! I love you!... I wrote on the train cars I love you, I love you! I love you!... I wrote in the sand I love you, I love you! I love you!... I wrote on the water I love you, I love you! I love you!... I wrote in the sky I love you, I love you! I love you!... I wrote in my heart I love you, I love you! I love you!... I wrote it... But maybe I still haven't understood what love is...
