Here’s what I said in answer to this in November: “Let’s just get one thing out of the way: It absolutely does NOT mean never having to say you’re sorry, Erich Segal’s Love Story notwithstanding. (For more on the profound interaction we call apology, read Aaron Lazare’s On Apology: BF575 .A75 L39 2004.) There are at least as many dimensions to love as there are words for it in all the world’s languages. In an answer last spring, I pointed out that the ancient Greek word “agape” means love that expects nothing in return: bit.ly/AW-agape. I’ve also pointed out that it’s helpful to recall that love is a verb, and calls you to do things for people: bit.ly/AW-love-feeling.”
