_Slanting mouths_ indicate trickiness, "foxiness" and general unreliability. _Crooked mouths_, or mouths greatly out of symmetry, are held by many authorities to indicate lack of Conscientiousness, and often criminal tendencies. _Full, red, middle-lips_ indicate love of the opposite sex. _Thin, pale middle-lips_ denote the opposite traits. _A long upper-lip_ indicates Self-Esteem. _A short upper-lip_ denotes deficient Self-Esteem, but often also a strong Approbativeness. (John D. Rockefeller has an almost abnormally long upper lip.) The affectionate faculties are believed to manifest in outer form in the center of the lips, because of certain nerve centers at that place. A fullness and enlargement there denotes strong affection, while deficiency in the affectionate qualities manifest in the opposite direction. Will and self-control is shown by the relative firmness and "set" of the lips and mouth. Besides the above mentioned characteristics, the student will soon perceive that there are certain "expressions" of the lips and mouth which, although impossible of expression in words, nevertheless may be almost instinctively recognized by the careful observer. Lips, like eyes, tell their story plainly to the careful and practiced observer. It is a safe rule to _avoid those whose mouths arouse an instinctive distrust in your mind_. Watch closely the mouths of people speaking to you, and you will receive many a plain signal of danger, and many an assurance of safety. The eyes, while full of information, often deceive those not fully versed in their secret code--but the mouth tells its tale in plain, simple, understandable terms, signs and symbols.
