Considering the culture and the circumstances, people have come to truly and sincerely believe that love can be found in receiving toys, flowers, and candies; or replacing lovers like one replaces tires for their car. Replace them until you sort of think you like what they give. Taking things is not love, that is greed.
Love is a forgotten trait in this day and age. Love has been superseded by lust, and everyone thinks that the feelings of lust already constitutes love. And that is why people "fall out" of love often, and make breaking hearts look so easy. Because they never knew what love is.
Love requires one to give without expecting anything in return. To forgive without expecting to be forgiven. To be patient when the other has no patience. To be kind when the other will only hurt. To remain loyal when they are not. To care when they do not. To be compassionate when they are not. To remember when they forget. To remain when they move away. That is love, and love is not easy. It never was, and it never will be.
