“Love,” as many have mentioned, is a tremendously overused word. People say they love movies, books, dogs, cats, handbags, food, weather, cars, bicycles, shirts, skirts, vacations, . . . . you name it and, odds are, it’s loved (or hated). But actually, only mothers love, and they love only their children. Only mothers have essentially unconditional care and regard for their children who, without it, would die and the species would not continue. All other relationships are something else: lust and like come to mind.
