Woman in her 60's: I want a timeline of the history of mankind.
Me: Can you narrow that to a specific time period?
Woman: No, I want it all in one book. From the year 4026 BC to the year 8000.
Me: We haven't reached the year 8000 yet. (Come back in 6000 years- you still won't be able to find such a book).
Woman: Just tell me where the timelines are and I'll find it.
Me: We probably don't have books specifically with timelines, but I bet I can find one about the history of the caveman, etc. in each era.
Woman: No, it has to be all in one book. Events that took place every day from the year 4026 BC until today.
So I showed her the area where World History books are, and she seemed happy as a clam. I wonder what's so special about 4026 BC?
