If anyone knows how it feels to be so darned happy, infatuated and out of your mind in love, it's you. So when you pass by someone (or two someones) with 'that look' on their face, toss them the same look in return: or offer up a nod and a toast from across the room. They'll get it. Happiness and love are contagious, and you'll have more amorous offers than you know what to do with.
