Which is exactly why, back when I was writing software, when *I* thought 
I was done, I always stood up and handed the keyboard & chair to 
someone else.  Thats usually quite a humbling comuppance when you 
suddently realize that even if *you* understand it, you are not sending 
a sufficiently clear msg to the user.  So you have to idiot-proof your 
work, and then hope a smarter idiot than you doesn't come along and 
break it.  Because he will, just as sure as taxes coming due...
