EMILY: Richard, don’t you dare get on that phone. They’ll be here any second.
RICHARD: I’m not getting on the phone. I’m going to give Rory that first edition of Mencken’s Chrestomathy.
Mencken’s Chrestomathy was earlier discussed as a book that Richard called Rory about after they first bonded at Richard’s country club. A first edition is difficult to find and would most likely cost more than $100 today.
The special family dinner may be Friday June 1, meaning that the school year just finished for Rory, and they are celebrating the end of her first year at Chilton, and the success she attained during it.
