I am unable to understand people who often visit libraries. In my opinion, it is really very strange. I don\'t think libraries are interesting places and librarians are fascinating people. They are usually not very young ladies who tell you what you must or mustn\'t do. You can\'t be active or cheerful in the library. I prefer to find the information I need at home, using my wonderful computer.
