Short, quick and clean - not my favorite story, but certainly well told and enjoyable. Once it was stated that his mother was going to punish him, the ending became rather predictable - but hey, I don't get to call them correctly very often, so I'm not going to complain. Great Shark Week jokes too.
The ending got me thinking, though - if everyone has a button, what kind of society is this? Are there any real people left, or is everyone a "toy" with a button? Is there's some company that manufactures people and then advertises them to their creations that are already out in the world? If so, aren't they solely responsible for the continuation of the race? What an odd life cycle... How did this process all start, anyway? Perhaps learning about one's own button is like a right-of-passage, as now one can see the world for what it is. Can the buttons be disabled when one reaches adulthood?
Any story that gets me thinking that much was obviously worth my time
