Back when I was in school -- this is before people had wide access to the internet -- if I was going to do a research paper, I would have to physically walk to the library, and if they had the book that you needed, great.
Na minha época de escola, antes de as pessoas terem amplo acesso à internet, se eu tivesse que fazer uma pesquisa, eu tinha que caminhar até a biblioteca e, se eles tivessem o livro que eu queria, ótimo.
