This happens to me occasionally either when I’m on the sidewalk or in the subway. It’s rather inexplicable when it happens. Somehow these people manage to slowly and efficiently block precisely where I want to be walking. I’m not talking about just taking one or two steps here. I’ll come to a stop, see that the person is slow and then try to go around and right on cue they’ll step right where I was about to go to go around them. At which point there’s often no room on that side anymore and sometimes they’ll even move in the other direction when I move. These people were clearly put on this earth to irritate me so they could get a comic made about them.
