The invitation says, "Bring your favorite side dish." Hmmmm. Mashed potatoes? Too boring. Spinach souffle? Too puffy. Mini meatballs? No, you don't want anyone to know that you eat those. Maybe something with cheese... and then you remember that the hostess is lactose-intolerant. You're on the verge of being stumped when you catch that delicious and familiar scent in the air. It's the fragrance of festivity and you're gripped by the party spirit. "I shall bring champagne!" you proclaim. That counts as a side dish, doesn't it?
