"Change" is the key issue in this well-written short story. But the most difficult part regarding change is how to defy and challenge our will when we have already taken everything for granted and are accustomed to the constant.

Francis Bacon once said something like that "People commonly think according to their inclinations, speak according to their learning and ingrained opinions, but generally act according to custom." That's why changing the way we usually do is not a simple thing- it's against our human nature- a complex human being often makes things complicated. So, "keep things simple and stupid" might sometimes be a good and quick way to rule out any unnecessary worries.
