You are maturing and learning how to be responsible without being boring or maudlin. You're also changing the way you appear to others, which may rub some the wrong way. No matter. You know who your friends are. In truth, they're the ones you're inviting over for a spontaneous dinner party. This week? Tapas. Try crab cakes with orange-dill sauce and roasted olives with fennel and lemon served before a heaping helping of paella and a Spanish rioja.
