when I am proud and a friend dares to stand out to warn me that I should keep modest, he is my closest friend; and, when I read Old Man and the Sea, I think Hemingway is my best friend. You see then, how many closest friends I have. But I must say, though I always want to keep all of them in my heart, they are not actually always in my heart. They have their own friends and their own life. Winston Churchill once said that there’s no perpetual friend, nor perpetual enemy, only perpetual interest. I guehe’s right in some way.Personally I think it is a shame for people who take a pet as his closest friend as this is a sheer insult to human being and an absolute indignity for the word FRIENDSHIP. If a dog is his closest friend, what is human to him? You can imagine how would a person with his ANIMAL closest friend do to PEOPLE. And maybe sometimes a dog can give him mental comfort, but what a dog likes best is just a bone. Friendship is indeed an inborn desire of mankind, and it is relationship between people, not between people and animals. If you seek friendship, please seek it from people, from people around you.Actually I have much more to say but… your criticism welcome!
