THE NEIGHBOURS BEHIND MY NEW HOUSE

After I had gone to do some rechecking of the Feng Shui of my new house, I drove around the housing estate. It was then that I noticed that the wife of the neighbour behind my house had left her car door open and had also forgotten to switch off the backlights of her car.
I decided to stop at their house and inform them about the matter. Actually I have known the couple for some time now as they are my colleagues. The husband is a fellow teacher and his wife is the school clerk. One of the reasons that made me buy the house was because I knew that they would be nearby. Can you guess who they are?
