I see the big yellow machine. It’s moving slowly down the street. Its wheels make loud bang-bang sounds as they hit the ground. Inside, I can hear men talking and machines clanking. The machine is bigger than me! Its body is painted bright yellow with black lines that look like teeth grinning at me. A huge arm extends out, picking up trash from the sidewalk. The arm swings back, throws the trash in a big bin, then goes back to pick more. It keeps doing this over and over. I watch it for a long time, fascinated by how it moves so smoothly and neatly.
