Make the voice of a delivery boy Four dollars and a half. Climb the sixth floor. Three and a half dollars. The electric car is out of power. There are two squares left, one is flashing. The navigation says there are still four kilometers left. Can we ride four kilometers? Able. Just don't stop. Red light for seventy seconds. I put my phone on the handlebar and the screen was cracked but still bright. The order countdown is jumping, yellow and red. I stared at the number, my heart beating with it. Merchants are slow to deliver food. The clerk said "wait". I leaned against the wall and waited. I couldn't bend my knees, so I stood against the wall with my legs stretched straight. The customer's phone cannot be reached. I stood at the door on the sixth floor and knocked three times. The door opened and the old lady counted the change. Three and a half dollars. She counted it twice. She asked, "Are you tired?" And I said, "No." My knees were shaking when I went down the stairs. I stood holding the wall for a while, and the voice-activated light went out, and it was just me. Are you tired of delivering food? Tired. But there's no time to get tired. When the next order comes, you still have to run.
