Host Ira Glass talks with Kayla Hernandez, a seventh-grader who likes to reminisce about when she was a child, back in fifth grade. She visits Room 211 in her school, where her fifth grade class met, and looks at her old books, thinks about what happened there. She says she knows that decades from now, she won't even remember most of what's happening to her this year, in seventh grade, and that makes her sad. (5 minutes)
