emotion of love

Love is an important thing in the world no matter that is about family, lovers and friends. By the definition, it means a strong feeling of affection. It is a good and wonderful emtion that human have. There is no reason for this emotion only if you are creature. Even the animals, they also have love. For example, I ever read a mail about a sparrow. The sparrow stood on the road and watched its partner. The partner died because it was bumped by car. The sparrow stayed at its partner's side for three days and won't leave. In my opinion, love radiates naturally between something or someone you care. And this feeling will let us feel happy and bendictional.
