I am the only considerate person on earth.
If I did not move, people would walk right into me.
I had so thoroughly convinced myself that I am the only one who moves, that I decided to conduct an experiment...
"I am going to walk in a straight path on my side of the sidewalk. I will not move or yield for anyone."
About 10 seconds into my experiment....
I put my shoulder and hip into a tiny college student and knocked her back a few feet. After I said, "I'm sorry!"... I almost immediately started laughing. Experiment concluded.
Proving once again that I AM the most considerate person on earth.
