A very special cloud [Story]

On a small bridge that is for car training, I was just wandering around when I saw a cloud, is not a ordinary cloud, its inside was a rainbow. And I'm not using any drones camera stuff, the cloud just gave out the inside of them. It was like the 'Gate to Heaven' when it leaked out like a good person has passed away, and the other kids around there also saw it.
It was wonderful.
