I got this from World Magazine Blog (they were quoting columnist Nat Hentoff):

A longtime friend of mine is married to a doctor who also performs abortions. At the dinner table one recent evening, their 9-year-old son — having heard a word whose meaning he didn’t know — asked, “What is an abortion?” His mother, choosing her words carefully, described the procedure in simple terms. “But,” said her son, “that means killing the baby.” The mother then explained that there are certain months during which an abortion cannot be performed, with very few exceptions. The 9-year-old shook his head. “But,” he said, “it doesn’t matter what month. It still means killing the babies.”

Grace and Peace
