deep opposites

My fantasy about this untruthful world.

They sing but they scream.
They laugh but they cry.
They sleep but not breathing.
They smile but unspeakable.

They've the Sun but not the light
They've the moon but not the beauty
They've the eyes but not to see.
They've the ears but not to hear.

They teach you everything.
(But not tell everything)
They tell truth to you.
(But lied to you)

Who seek for friend?
He will lose friends.
Who need the trust?
He will not given the trust.
Who deserves the truth?
He will cry for the truth.

Who can't speak will never sing
Who never fell will never stand
Who never lies will never appreciate truth
Who never meet death will never find a life

Author's Note

Any advice for the grammar? Cause English is not my main language.
