I've realized, I think, what part of the reason is for my dislike of the last day of a trip. It's something I learned in high school physics. When measuring the distance an object travels, physics only measures the distance between where it started and where it finally stopped moving.

If it returns to the place it left from, even if it's looped halfway around the universe in the process, it hasn't traveled any distance at all.

The work is zero, and the Delta travel is zero.
