The Teacher Who Stepped Forward

I had better take care of my stomach, it may be a long day and I can not do my best work on an empty belly. So, I turn to the right and walk toward two slightly opened double doors. They creaked as I walked through. To my amazement the lunch rooms of the future do not have tables and chairs. They have only vending machines that disperse what looks like vitamins. The apple pie I smell is no where to be found. My nose leads me toward a small vent in the wall. It is only an air freshener!!!
