Studying in Paris was very inconvenient. The Bibliotèque Nationale was a long way off. Vladimir Ilyich usually cycled there, but riding a bicycle in Paris was not what it was in the suburbs of Geneva. It was a great strain. Those cycle rides tired him out. The library closed at lunch time,. There was a lot of red-tape in the arrangements for ordering books, and Ilych swore at the library, and while he was at it, at Paris in general. ... In the end his bicycle was stolen. he used to leave it on the stairs of a house next door to the Bibliotèque Nationale and pay the concierge ten centimes a day for it. When he came for the bicycle and found it gone, the concierge declared that she had not been hired to look after the bicycle but only to let Ilyich keep it on the stairs.
