Marvella Watkins Velle is a single mother of three children that includes two sons and a daughter. She has a full-time job and spends much of each morning riding the metro subway to take her children to school and then to go to work. The main train Marvella takes with her children is the Orange Line to Ballston, although her particular journey allows her to take a Blue Train if it arrives first as the Orange and Blue lines parallel each other along her trip. One day, Marvella's children strike up a conversation with a man who is also riding the train.
