Honestly, if they set something like that up it might be specifically to see what I would do. They may be dismayed, however, to find that my decision rested on whether or not I felt like pushing a button at the time. Did I push it? Perhaps the button looked very exciting and was just SCREAMING to be pushed. Did I leave it be? Perhaps I thought it might be dirty and I should just not touch it, or perhaps it was boring and I just wanted a delicious tuna-fish sandwich after this was all done with. Who knows!
