I am on the coldest bus in the world. It is so cold that all the windows, except the front windscreen, are misted over with condensation. It is so cold, I wish I had a jacket, even for a five-minute ride. It is so cold that when I boarded the bus, my body thought we had entered a space/time warp-portal: it felt like I had stepped off a flight to a temperate country, what with the frigid temperature and utter lack of humidity.
