May 15:

May 15th. The ill-tempered person . . . can make very little of his environment. However he may attempt to circumscribe it in certain directions, there will always remain a wide and ever-changing area to stimulate his irascibility. His environment, in short, is an inconstant quantity, and his most elaborate calculations and precautions must often and suddenly fail him. Natural Law, Mortification, p.191.
