All his movements are quick and fidgety.

He appears to walk principally on his toes, and seems always on the point of beginning to dance, or jump, or run whenever he moves about, either in or out of doors.

When he speaks he has an odd habit of ducking his head suddenly, and looking at the person whom he addresses over his shoulder.

These, and other little personal peculiarities of the same undignified nature, all contribute to make him exactly that sort of person whom everybody shakes hands with, and nobody bows to, on a first introduction.

Men instinctively choose him to be the recipient of a joke, girls to be the male confidant of all flirtations which they like to talk about, children to be their petitioner for the pardon of a fault, or the reward of a half-holiday.
