It's only 3: 30 in the afternoon, and it's as dark as 7: 00 in the evening. What happened?

That's because it is cloudy. There are many clouds in the sky, which block the sunshine. The sun can't shine on us at all, and that's it when it comes. It's cloudy, it's going to rain, and the clouds are rolling. How can it not be dark? In fact, it's already beginning of winter today, which means it's winter. It's just that the weather is going to change again today, so it's always dark. It's still windy here. We have to put on winter clothes and down jackets.
