Why is sandwich meat round when bread is square?
<|assistant|>
Sandwich meat is typically shaped by machines and is round because the machines often use cylindrical blades to shape the meat. The bread is square because it is cut by humans with a knife, which creates a flat and even surface. Additionally, the texture of the bread tends to retain its shape while sandwich meat can be spread out or pushed together to create different shapes.
