A school-age child who is unsupervised after school or in general due to his or her parents being away for work. I know it makes me sound horrible, but I just don't want Tommy hanging out with those latchkey kids from down the road. Being a latchkey kid was tough at times, but it taught me the value of self-reliance at an earlier age than most.
