The temperature suddenly drops. It's like Batman's mortal enemy, Mr. Freeze, who makes use of technology and freezes the whole city in one night's time and is not gradual at all. Saying that the city is frozen is exaggerating, but with the rain falling, it really is quite cold. After all, it's a fall of over 10 degrees Celsius. All of you going to work or school, it's really not easy to get out of bed! We'll work hard together!
