A little memory

Back in the day, when I was a kid, — the basketball court in our courtyard, the neighborhood. There was usually a movie in summer. The iron shelf used to hang the curtain; it was always there, stuck close to the concrete stairs （It's like 10 times better than the one in the image）. Children liked to climb it. I remember even when I was older, like in middle school, I could barely reach the third or fourth row, unlike some children who would go all the way to the top. And sometimes they would wiggle their bodies when they were on top of it.
