When I was going home today after the last lecture my lock to the bike had frozen. The key went in and all but I was unable to turn it. I gave up quite quickly becauce my hands became really cold, which made it harder. I was far from the only one with the same problem, but some lucky bastards where able to ride their bikes home in the snow. I wonder what kind of locks they have, maybe they had some special tric or perhaps they just are stronger than me. Anna-Giulia thought we should invent a new lock that works no matter the what weather it is.
