This Sunday was started sunny & warm. The afternoon is just like yesterday, bright day & blue sky; just another typical hot day. However, the face of sky changes so fast in the evening. When I was staring out from the window around 6pm, the atmosphere is completely different in color; it's a yellow world out there. Everything appeared like coated with a layer of yellow powder & I have a creepy feeling like end of world. I can see clouds are getting thicker & thundering is heard. When time passes, the sky is slowly switching from yellow to brown. I am feeling like living in fantasy where this scene could only appear in fiction. And rain starts to fall when it gets completely dark.
