Is it really only humans who feel love for others? It may seem so, but I've seen animals sacrifice their lives to save their offspring. Is it merely instinct to save one's own species, or is there some emotion involved? It's truly hard to say, and it's undeniable that love makes our world a better place. All these points you mentioned have made me reflect: what would my life be like without the love of close people? What would the world be like if love didn't exist? I couldn't imagine how bad it could be.
