Robert Heinlein

Women and cats do what they do; there is nothing a man may do about it.

Heinlein was born on this date in 1907.  This quote is from his 1985 novel, The Cat Who Walks Through Walls: A Comedy of Manners.  One of the characters in this book is Pixel, a cat who does walk through a wall -- Heinlein explains that the cat is too young to know that it is impossible.  You might write a book about a dog who dug under a wall, or chewed a hole through a wall, but you would never write a book about a dog who walked through a wall.  A dog doesn't have as much imagination as a cat.

Robert Heinlein died in 1988
