You and you-know-who are making tremendous advances on Monday. Perhaps literal advances -- you may be advancing through the sky on an airplane together, or speeding down he highway toward a new Thai restaurant. Tuesday and Wednesday, you won't be much in the mood for a date -- matter of fact, you won't be much in the mood for other people at all -- but Thursday and Friday are banner days in the social department. Laughter figures prominently. Your friends will be gushing over how much they love you. And you? Whom do you love? This question occupies you this weekend.
