I stared at cloud which moving slowly in the blue skies. I couldn’t help myself to sometimes felt asleep for minute or two. When awaked, I saw the cloud already change to blackish cloud, gloomy one. Stared again, and felt asleep again, woked up again, and change again to clearer cloud than before. Amusing scene.
Cloud doesn’t change I realized. It only moved and changed colour. Cloud never changed to rain, rainbow, nor sky. Each of them perform different roles. We could say, they are professional.
