i used to have a "comedy routine" i thought of to entertain myself. this was in my early 20's and i was not very mature then.
when i went to work in the mornings, there would be crowds of people to negotiate around at north sydney station where i got off the train.
there were 2 "lanes" of walking traffic. there were "oncoming people", and "people going in my direction".
it is difficult to overtake people walking in the same direction as me, because they do not know i am behind them. but if i veer out and walk against the flow of the oncoming people, they see me coming and get out of my way.
if i pretend to be absorbed in a newspaper while i am walking, they will nearly always get out of my way no matter how fast i walk.
i found a device once which seemed like a blind persons walking cane. it was made of aluminium, and had a little plastic ball at the end of the slender aluminium rod. (it was laying against a wall at the doctors).
anyway, i experimented with wearing very dark sunglasses, and i used this "proboscis" stick like a blind person in order to see how easily people got out of my way when they think i am "blind".
they got out of my way very well.
then one day, i had a girl with me, and i imagined a scenario and told her about it, and she begged me to do it.
the scenario was that i was running at high speed with dark sunglasses on, and whacking my stick frantically in front of me as i ran.
i would run at my true (sighted) top speed, but pretend i was blind, and whack the walls of the tunnel into the train station with my stick, pretending that i was being guided by only that feedback. then i would flail my stick wildly to find the staircase and and handrail (in rapid time), and i would descend the stairs athletically, as if i was using only the flailing cane as my guide. people thought some crazy thoughts that i could not determine from their expressions.
melinda was very much propelled to fits of laughter. we were almost arrested and we were told never to do that again.
i did not do it many times after that.
