The Perks of Being a Wallflower
From 2005 to 2009, Perks appeared on the American Library Association's Top 10 most frequently challenged books list. It peaked at #3 in 2009. If there were a bronze trophy for being challenged, what would it look like? (Source.)
Charlie probably wouldn't be caught dead listening to Top 40 Hits on the radio, but if he did, he might have heard some of these hits of the 90s, like Bryan Adams's "(Everything I Do) I Do It For You." And then he would promptly change the station.
Charlie sends 52 letters, averaging out to a letter a week. A stamp (that's a little sticky square you put on a letter to pay the post office to carry it to its intended destination) cost $.29 in 1991, so it would have cost Charlie $15.08 to mail all his letters. Where was e-mail when he needed it? (Source.)
Stephen Chbosky wrote the screenplay for the film adaptation of Rent. Both stories are kind of emo—and totally amazing—so we're not too surprised. (Source.)
