I am reminded of a story from my younger days. I worked with a woman who went in to the emergency room one night for "stomach cramps" and came out with a baby.

If she was to be believed, even she didn't know. She'd always had very unregular periods and she was heavy enough that no one she worked with noticed. Maybe it was a secret because the father was another (married) co-worker, maybe she actively didn't want to know. Hell, maybe you can be preggo and not know, who am to say? Anyway she gave birth to a perfectly healthy son. If course people asked her "how?", and she said she "thought what must've been kicks were just gas"

That was over 20 years ago, dunno why this reminded me. hot damn, that kid is a grown man now
