Think brothers, sisters, and friends since childhood. Think Sponge Bob and Patric, some nuts and spice. Think Pisces and Scorpios. Or Apple and Steve. Think Holmes with his Watson, rum and some raisins. Think PB and jelly sandwiches, or mac and cheese for dinner. Think red think full, think white and light, and wine while you dine. Think chocolate with chocolate, pumpkin in a pie, or just tea and cake. Think toddlers with paint, and teenagers with selfie sticks. Think plays and Shakespeare. Think Wyatt and Surrey, and a cupboard underneath the stairs. Think blueberry and pancakes, bacon and eggs. Or, just you and I — the perfect match.
