Today some classmate and I served at the Capital Library as volunteers. At 9 o’ clock we gathered at the gate of the library. After getting into the library we first trained by a librarian on when to operate the computers to borrow or return books. Then wear the volunteer uniform we got down on our work. Some helped put books on the shelves but some offered assistance to the people who had difficulty using the computers. All of us took our tasks serious.
