Sometimes it is difficult to live with other people and to discuss in the darkness. Only words might be clue to communicate, but it also brings misunderstandings. When my first son couldn’t speak much, I used to say to my wife that I could understand my dog better than my little son. Then, she said I depend too much on words to understand. However, if you don’t need any words to communicate with other person, you can exchange some idea even with your dog. Indeed, humankind can understand each other because they’re same kind. It can hardly adopt this to Middle East, though.
