The difference between a stone played on one intersection rather than on an adjacent neighbor is insignificant to the uninitiated. The master of Go, though, sees it as all the difference between a flower and a cinderblock. Certain plays resonate with a balletic grace, others clunk, hopelessly awkward, and to fail at making the distinction is a bit like confusing the ping of a Limoges platter with the clink of a Burger King Smurfs tumbler.
