I was walking down the street, I needed to go to the grocery store and get a couple things for dinner. There’s a wide alley type area where people walk their dogs and also the garbage truck comes through here. Normally there wouldn’t be any one out there so late; but today must have been special. One person was breaking down cardboard boxes to put throw away occupied, working carefully trying not to get cut. I wasn’t worried about the first person, they were totally occupied. The second person was sitting in a lawn chair waiting for something or someone and also talking on the phone. I really didn’t want to have another exhausting conversation again with one of the neighbors; I was out here standing for half an hour “catching up”. I was walking fine at first, my head was forward and my stride was steady. As soon as I passed the second person I felt like they looked up and I suppose I forgot how to walk. I literally tripped myself; I tripped over my feet, my feet. I landed on my stomach but I feel like I slid a couple feet as well. I had headphones on so I pretended to tie my shoes and kept walking. I hope no one saw that.
