SECTION 45. To speak angrily to a person, to show your hatred by

what you say or by the way you look, is an unnecessary

proceeding--dangerous, foolish, ridiculous, and vulgar.

Anger and hatred should never be shown otherwise than in what you do;

and feelings will be all the more effective in action, in so far

as you avoid the exhibition of them in any other way. It is only

cold-blooded animals whose bite is poisonous.
