For some parties, the guest list should be kept really short . . . say, just two people. Your significant other’s birthday could be one of those occasions when you show your partner a totally different side of your personality. You don’t have to look like a lingerie model, but it might be fun for both of you if you slipped into something sexier than what you normally wear. You could cook a gourmet meal, set the table for two, and then get dressed to meet your partner when he or she comes home from work. You’ll both rediscover how exciting a birthday party can be!
