Which one is the blind?

This time my words stopped at two men
Under a leafly, shadowy and grand tree
A worm breeze accompanied with cruckles of leaves
Close from a calm and steady lake
Where started the scene

Sitting side to side, each having a sigh
One with beautiful round eyes
Contemplating each person passing by
gratefully offering a smile

The other stood firmly
No facial movement with a puppy liking his arm
Pale and lost in an abyss of dilemmas
Regretting the moment he was born
With all the joy surrounding him
Colors, shapes and even motifs

Because of black glasses, people are often mistaken
Saying: which one is the blind?
