Some of the best times in primary school were spent on the playground. The sweetest of those was when the last bell rang and we ran out to the front of the building where we would frolic until our parents picked us up. The only thing that dampened our time was being under the supervision of one woman. Most impressive of which was not her size or her booming voice when she yelled across the compound, it was her face. She had this permanent menacing scowl and it terrified us. From where she sat, she could see every corner. We did our best to keep a clear perimeter around her. It was only during a pleasant interaction a few months before I headed of to high school that I realized that that was just her face.
