40 floors to go, walking confidently through the cacophony, dressed up fancily, anyone who attempts to question us we simply ramble on in English, Swedish and Ukrainian while keeping it moving. Reaching the top floor, there is no way for us to access the roof. Searching, we find a small hole high up in the ceiling, barely the size of our bodies. We manage to climb through it, removing clothes to fit. On the roof we free climb another 30 meters to finally we stand on the edge of the tallest roof in Mexico and whole South America.
