Mark Twain Quote

When grown-up persons indulge in practical jokes, the fact gauges them. They have lived narrow, obscure, and ignorant lives, and at full manhood they still retain and cherish a job lot of left-over standards and ideals that would have been discarded with their boyhood if they had then moved out into the world and a broader life.
