Mark on the Wall Exercise: The Block on the Wall

There is a block on the wall, what could it be? It resembles a piece of molding made of plaster or wood. It could also be the remnants of an old speaker box for which communication could have been made. Who would have used the speaker box? Could it have been used by the dean or the administration office? Or, it could have been used by the professor? But, what if it is not a speaker box, it is just a piece of molding. Then, why is it there? It just sits there all alone. What lies beneath it? What secrets lie beneath this piece of hard heartless wood? There could be a hole behind the block that looks into another room. The hole could have been made by an angry student who punched a hole in the wall, or it could have been made by an earthquake or tornado. But that scenario is improbable because there aren’t serious earthquakes in Indiana, and if there had been a tornado it would have destroyed the whole building. Why is that block on the wall and what secrets about the past does it hide? I will never know because I am not tall enough to reach it and I don't have a ladder.
