LAUGHS
Laughter is full of the expression of character. One may often accurately determine the character of a person whose face is not seen or known. A hearty laugh is indicative of sympathy, companionship and general sociability, as well as a well developed sense of humor. A giggle is indicative of pettiness, trifling and general mental light-weight. The repressed laugh shows self-control and often caution and cunning, the tone denoting the difference. The vulgar "haw-haw" denotes a correspondingly gross nature. The peculiar shrill, rasping, parrot-like laugh of the courtesan is typical, and when ever heard should act as a note of warning. It is difficult to state in words the various qualities of the laugh, but each is distinctive and well expresses the Quality causing it. It may be said that each and every mental Quality has its corresponding note in the laugh, which note may be learned and recognized by a little practice and actual observation.
