My mind is a bit loopy of late since I'm buried waist-deep in student essays. However, that hasn't stopped me from this confusion.
Why are bologna, salami, and provolone cheese round but bread is square? The final product is rather odd and not at all visually appealing.
Why is it called trimming the tree? The object should be to decorate not cut.
Why is something called a drive-through when one has to stop at the window? Brakes need not be applied.
