Holy shit, my dad was right: cut your sandwiches like triangles, not at a 90 degree angle. My mom used to always cut them across the middle, making two rectangles, while dad did it from corner to corner. Mom always looked at him with pity and distain: how could he do something so wrong? Dammit, woman, he was fucking right. I have new respect for my father - he was rarely in the kitchen, but he sure knew how to cut a sandwich.
