The following story comes courtesy of one of my classes in elementary school in either 2000 or 2001. I do not remember the subject of the class or the events leading up to this particular anecdote. My teacher crafted an example to make a point about memory. She told the class that if she told one of us to go to the neighboring classroom to borrow a tube of blue paint, we would not long remember her instructions after completing the task.

My teacher did not say anything about whether we would remember hypothetical tasks.
