In most situations, words are my weapon--when it comes to convincing people how to love, though, I don't think that using a weapon is the best approach. If the entire world disagreed with me, arguing wouldn't get me anywhere.
Instead, I would show the people in my life what love really means, day by day. Isn't this what we already have to do? It's not enough to just say the words "I love you" as if they're an obligatory ritual. It's not enough to feel butterflies and passion, because those eventually fade.
Love is sacrifice. Love is patience. Love is putting another's needs before your own.
It doesn't matter how the world might choose to define the word "love." There are already dozens of definitions that exist today. What matters is how we care for people, and how we connect as a result. Even if the world disagreed with how I defined "love," they would still feel the impact of selfless actions and kind gestures, which stem from a caring heart.
Love is more than just a definition.
