Well, it's kind of the obvious discussion to have when one or more of one's parents have LiveJournals.

I mean, I think there are actually four or five people on my friends list who have been friends of my parents continuously since before I was born, and therefore might be able to be considered to have known me pre-nataly.

Of course, this whole discussion is NOT counting people who've known each other in past lives and so forth -- THAT could get even LONGER.
