Who are you?

Tell me quietly who you are.
Say to me your name.
Caress me with the tips of your worries
And slowly sink goodbye, to the darkest of the sides.

Say hi to them, and come up quickly,
Before they come and squeeze you tight.
Learn to laugh, know it will be the best of your qualities
But at the same time, your biggest fear

Be smart, it's just that much easier to do
Learn your wicked smile, you might need it
What? It's true
Say to me your name
Say to me goodbye

"Goodbye my friend, bye bye"
His eyes are closed
His breath is still
Who is he?
He is my demon, he is a sin
