Here's a couple of koans we just made up for you in the office:

The newbie programmer went to see the DBA and asked how do I know if the data is really normal? The DBA pulled the plug on the server, and the Newbie was enlightened.

The fan hums
The keyboard clicks
I see the blue screen of death
I must reboot

Jim's was neither nihilistic or existential, because he didn't post. Mine was incomplete:
FUNCTION isTrue(llTrue)
RETURN IIF(!isTrue(isTrue()),.T.,.F.)

, and yours was Zen with an existential acknowledgment. To get an answer here is going to require some plain language philosophical answer, because until we figure out what "message" "thread", and "Not" we can't post a response.
