It's sexy as hell. What does it mean to be in caffection? Does it mean you’re suffering from some exotic, long-term condition? Well, yes and no. If you’re in caffection are you damaged in some way? Well, not damaged, exactly, but certainly on the shelf. Are you deranged? Out of touch? Had a tad too much coffee? It's one of those inscrutable things. But the beauty of the word is that if you have it, you know it. It lends itself to the lucky few couples who just know.
