Жизнерадостный ребенок (1912)

Set in a tenement boarding house, a lonely confirmed bachelor occupies a room across the hall from a dour spinster. Children run amok in the hallways playing pranks. Believing the bachelor perpetrated one particular prank, the spinster woman enters his room to confront him. She is followed by a neighbor child. Meanwhile, the other children have stolen a scarlet fever quarantine sign and posted it on the bachelor's door.
