I was skating this morning when I encountered a most interesting situation that reminded me of an online discussion at a certain blog I visit.
A woman was walking west on the sidewalk along 16th Street's westbound lane, as I was skateboarding east (approaching her) also in the westbound lane. A few steps in front of the woman and just to her right sits a pad of concrete that I occasionally like to "ollie" up on and off while in transit. It's fun! However, the woman did not know that I occasionally do this. So, when I ollied onto the sidewalk headed for the concrete pad, she flinched and tried to get out of my way, as she obviously thought I was going to run into her.
