“A writer who writes, “I am alone” ... can be considered rather comical. It is comical for a man to recognize his solitude by addressing a reader and by using methods that prevent the individual from being alone. The word alone is just as general as the word bread.

—Maurice Blanchot (b. 1907)
“For better or worse, stepparenting is self-conscious parenting. You’re damned if you do, and damned if you don’t.”
