Interesting quote from a signature lines

[David Farber <farber () central cis upenn edu>]

"...when a person in a Japanese firm sits quietly, no one will come and inter-
rupt. It is assumed that the person is thinking... when the person is up and
about,coworkers feel free to interrupt. Isn't it interesting that it is exactly
the opposite in American firms? In America, we assume that when a person is
sitting quietly they aren't doing anything very important."
