I find myself in this situation a lot. Stuck behind some slow-ass person on a narrow walkway/sidewalk. There should be designated lanes for these people. Just because you are not in a hurry to do anything with your life doesn't mean I have all day to stare at the back of your head (which by the way I often want to punch) while I am doing the equivalent of tailgating you! Move the FUCK out of the way... please!
