People who walk slowly and generally without concern for others in public. This includes, but isn't limited to:
- Stopping at the bottom of an escalator to check your cell phone.
- Walking slowly in a row (as opposed to a column) on a narrow sidewalk.
- Generally not paying attention to where you walk. My girlfriend is blind and she often ends up shoved to the floor by jerks who don't pay attention. (Or, sometimes, she will trip the inattentive pedestrian with her cane.)
I'm getting my jimmies rustled just composing this post. Navigate compassionately and to the best of your abilities in public or do not go out at all. Period.
