Harold's post above reminds me of a tech support call I recently heard about. . .
Customer: My computer shut down and won't come back on.
TS: Can you look to be sure it didn't become unplugged accidently?
Cust: No.
TS: Why not?
Cust: Becuase it's dark.
TS: Can you turn on a light?
Cust: No.
TS: Why not?
Cust: Becuase the power is out, and the whole neighborhood is dark.
