The Most Bumped Into New Yorker by other New Yorkers

Why is it whenever I walk down the street, no matter how much I stay over to my right, someone invariably bumps into me? I am the "Most bumped into New Yorker by other New Yorkers" I know. I walk to the right, I don't weave, I give up room when necessary, and still, somebody bumps me more than just a glancing blow. Perhaps it's a territorial thing for people--they don't want to give up an inch to anyone. They're high chargers; go-getters; 'get the flock out of my way, David' kinds of people. And here am I, just wanting to go from point A to point Z and the rest of the fucking alphabet is filled with bumps and bruises.
