It's better to talk to a deaf man
Than talk to a person with a deaf heart
It's better to walk with a blind man
Than walk with a person whose eyes can see but are oblivious
A deaf man cannot hear the words you speak but strives to connect with your feelings. We know that "listen" and "hear" are two different things.
A blind man cannot see but uses his senses to know what is happening around him. He still can lead the way for he has a direction.
