When your eyes start hurting and feel irritated, then you know something is wrong. And of course, when you hear the wind rattling around the corner of the house, you really know something’s wrong. And then, when you look out of the window, and you see how the sky has turned yellowish and everything is wrapped in a thick cloud of dust, that’s when you know: it’s a sand storm. And trust me, sand storms are no nice things. You know why when you see the layer of dust slowly descending onto every surface in your home, and when everything you touch feels a bit more slippery than usual, because it’s covered in tiny fine little grains of dust.
