Well, if I start putting my hand on the "inside" wall, then going in,
that's my left hand, and I go down, then I turn right at the corner and
proceed across to left of screen, and then again rotate right 90 degrees
and head up the screen, and then again to the exit, and I make it out just
fine! Now if I use my right hand, I simply take the same route backwards.
What in the hell are you talking about!!! And anyway, you ARE wrong. This
is a theorem in topology and finite math.
