Look up at the World

I am three centimeters tall. A blade of grass is like an ocean, the dew falling is like a heavy rain, and the ants rushing over are like a ferocious beast. I crossed the sea of ​​grass and walked into your city. When I looked up and saw the soles of the first pair of giant shoes, my legs were shaking. But I didn't retreat. My mother is still in your world. I want to find her.
