Jerry, everybody does something well, and nobody does everything well. 
Honesty is the best policy, the truth shall set you free.  The cane explains 
why you do what you do, and why others do what they do.
I get near the men's room by asking the waitress to direct me, taking her 
arm and holding my cane to the door.  Inside, I know a couple of things.
If it isn't the size of a home bathroom, the sinks are near the door, with 
the urinals placed around a wall, so if the door is opened, nobody sees.  If 
I don't hear anybody, I explore, if I do I ask.  The cane will find what I 
don't want to touch.  After years of struggle, I have learned that the more 
comfortable I am in asking, the more comfortable people are with answering. 
So I'll ask towels or blowers?  Where do the towels go?  Stalls are easy to 
find anyway.  I wouldn't do any of this with out a cane, because the cane 
explains why I am asking.
