The Office may have ended last spring, but Olivia, an 11-year-old from Portland, Oregon, is just catching up on all of the episodes now. The little viewer recently gave B.J. Novak (who acted and wrote on the show) a very nicely organized list of all the lessons she learned from the series and the whole thing is pretty freaking adorable.
It's hard to imagine anything more satisfying ("that's what she said." — never forget) than receiving a letter like that.
