D.W.'s Library Card & Arthur's Big Hit

D.W.'s Library Card: D.W. learns how to write her name to get her first library card. She also learns about borrowing books.
Arthur's Big Hit: Arthur punches D.W. on her arm for tossing his model airplane (that he worked on for a long time) out the window and mistaking it for a real flying plane, but ends up feeling what D.W. feels when Binky hits him on a dare.
