(I have long been accused of having no motherly instinct. As near as I can tell, this instinct consists of attempting to wrap anyone below the age of eighteen in swaddling bands, so that they never learn anything about the world and its dangers. I fail to see the use of this, especially from the point of view of species survival; but I do confess that on this occasion I may have let my intellectual excitement distract me from the peril of allowing a ten-year-old boy to wave a loaded rifle about.)
