The relationship of love is also unique. In the absence of love and greed, sometimes they go away and sometimes they become alien.
Love, affection, respect, importance, trust is the key that human beings, but animals and birds also come close to your heart. See the picture of a hospitalized patient. The nurse who has taken this picture told that this old patient has been admitted to the hospital for 3 days, and during these 3 days, no member of his family came to take care. But a pigeon comes for 2 days and goes to sit on their bed for a while!
Later it was discovered that he used to feed the pigeon sitting on the bench of the park next to the hospital.
