There is a mass of dark clouds in the sky.

As far as the eye could see, nothing could be seen except cornfields.

The sea is deep blue, and from afar it looks like a vast sheet of silk spread out.

I tripped in the alleyway in the darkness, as I crashed my knees on the asphalt. There was a wooden board that covered a wire between houses across the alleyway. It was very dark there at night. My eyeglasses fell off my face. Luckily, a Cantonese labourer with a flashlight helped me. My knees just got scraped. I remember another time when I crashed on my knees. It was at Don José Heights in Quezon City in the Philippines. There was a vastness of Martianesque red soil, wherein the "talahib" grass grew. Sometimes, workers intentionally set the grass on fire. My brother and I were still playing, even then, outside. We were still prepubescent. Near burning grass, I stumbled on my knees. My grandmother, Lola Bebe, was so angry. A maid washed my legs in the big tiled sink behind the garage.
