Infatuation is one of those slightly comic illnesses which are at once so undignified and so painful that a nice-minded world does its best to ignore their existence altogether, referring to them only under provocation and then with apology, but, like its more material brother, this boil on the neck of the spirit can hardly be forgotten either by the sufferer or anyone else in his vicinity. The malady is ludicrous, sad, excruciating and, above all, instantly diagnosable.
