Brain Learning:

I was mentally prepared for the fact that the driving was opposite in Australia from the United States of America.  However, I was not prepared that walking and moving around in public would be opposite as well.  You walk on the left hand side of the side walk.  You enter restrooms and buildings on the left (I don't know how many people I have almost bumped into going in or out of the "toilet". 

Opposite Escalators:

There were two opposing escalators side by side and I stood in front of the one on my right for the longest time trying to figure out what was wrong.  It was coming down at me, not going up.  I was trying to get onto the down escalator, but I wanted to go up.  The up escalator was on my left, not my right.  My brain is adjusting to this new way of moving and making those new pathways in my brain to help get me around the city safely.  It is such a thought process though.  I am appreciating the cognitive feeling of learning a new way of doing a similar task though.
