Leaving Chaswick

We meet two main characters in the first section of the book: Amelia Sedlak and Miss Becky Sharp. It opens with the two young women departing from a ladies' academy: dull, sweet Amelia (rich) and fiery sharp-witted Rebecca (poor). The book details much (in 18th century fashion) about the send off that the school mistress, Ms. Pinkerton, and her daughter/niece (?) Jemima put together... about how they are going to miss Amelia because she is the sweet popular one, full of joy, etc. It's clear that the girls were treated differently at the school, Becky worked and went to school, Amelia was sent there because of her families wealth. Jemima wants to send Becky with a copy of the Johnson's Dictionary (I guess it's a gift that all well bred girls receive when leaving the school) as she goes, but as Becky departs she whips it out of the carriage back at Jemima. Everyone is appalled.
