Home in no time

A woman was waiting in the checkout line at a shopping center. Her arms were heavily laden with a mop and broom and other cleaning supplies. By her actions and deep sighs, it was obvious she was in a hurry and not happy about the slowness of the line.

When the cashier called for a price check on a box of soap, the woman remarked indignantly, "Well, I'll be lucky to get out of here and home before Christmas!"

"Don't worry, ma'am," replied the clerk. "With that wind kicking up out there and that brand new broom you have here, you'll be home in no time."

Sir Patrick Geddes

Born 2 Oct 1854; died 17 Apr 1932 at age 77.Scottish biologist and sociologist who was one of the modern pioneers of the concept of town and regional planning. He studied under Darwin's champion, Thomas Henry Huxley. As a professor of botany, Geddes emphasized the development of sexual reproduction as a major step in organic evolution and, with the naturalist John Arthur Thomson, published The Evolution of Sex (1889). Geddes turned his attention to sociology after an attack of blindness in Mexico hampered his biological experimentation. His researches in India, Palestine, Mexico, and Scotland led to his conviction that the development of human communities was primarily biological in nature, consisting of interactions among people, their environment, and their activities.
