So this guy goes for a walk

So this short story that Bradbury wrote was made from something that happened to him in real life. In the story this guy named Lenard Mead liked to go for a walk and a police officer came up to him and took him away. This happened to Bradbury to just because he was walking. This drove to the creation of "The Pedestrian" based on his life. This affected the tone because it made it seem more real because he lived it and know what it felt like.
