schoolboy - a boy who goes to a school, usually a public school.
As such he will probably have a schedule that might instruct him to go to math class, English class, and science class at x, y, and z times. When school ends a schoolboy will usually return home via bus (which has inflexible arrival and departure times), bicycle, walking, or car. If by car, and the schoolboy is too young to drive, then his parent will usually drive him (with a car that consistently arrives at a specific time such as 3:00).
English schoolboy Joshua Clark died after snorting heroin from a bag that he found.
