No sooner is your son and heir invested with the full dignity of knickerbockers than he begins to celebrate this rise in the social scale by "playing at being papa." The author of "Vice Versa" has drawn an amusing picture of the discomforts to papa which an exchange of environment with his school-boy son might involve. But there is another side to the question; and at Christmas-time, for instance, most papas would probably be glad enough to exchange the joys and responsibilities of paternity for the simple taste which can tackle plum-pudding and the youthful digestion for which this delicacy has no terrors. However, while it is impossible, or at least inexpedient, for papa to play at being his own urchin, the latter is restrained by no considerations, moral or otherwise, from attempting to personate his papa. It is often said sententiously that the child is the father of the man. In this case most of us should blush for our parentage. It will be conceded at once (subject, of course, to special reservations in favor of individual brats) that the baby is the most detestable of created beings. But its physical impotence to some extent neutralizes its moral baseness. In the child the deviltries of the baby are partially curbed, but this loss is compensated for by superior bodily powers. Now, the virtuous child--if such a conception can be framed--when representing papa would delight to dwell on the better side of the paternal character, the finer feelings, the flashes of genius, the sallies of wit, the little touches of tenderness and romance, and so forth. Very likely; but the actual child does just the reverse of this. Is there a trivial weakness, a venial shortcoming, a microscopic spot of imperfection anywhere? The ruthless little imp has marked it for his own, and will infallibly reproduce it, certainly before your servants, and possibly before your friends. "Now we'll play at being in church," quoth Master George in lordly wise to his little sisters. "I'm papa." Whereupon he will twist himself into an unseemly tangle of legs and arms which is simply a barbarous travesty of the attitude of studied grace with which you drink in the sermon in the corner of your family pew.
