Which Came First?
A colleague of mine, Carol, was recounting to me today about how she answered her eldest daughter, who was only just a few years old at the time, when she asked her then-pregnant mother, "How did that happen?"
"Well," Carol replied carefully, "A mommy has eggs..."
She wanted to hit the technicalities but not necessarily the details, "...and sometimes a mommy's eggs get fertilized. When that happens a mommy gets pregnant with a baby."
Her daughter's eyes grew wide with surprise, "You mean...I was once a chicken?!"
