What was in the sky

When I was thirteen, a late-night walk with friends and my little brother turned into something none of us could ever explain. A circular object appeared in the sky—silent, lit with windows, and spinning unnaturally. It didn't just move. It turned. And then... it disappeared. We told our parents, but their disbelief only added to our confusion. No one believed us. But we remember every second of it—and sometimes, I wonder if we were supposed to see it at all.
