First off, there's mention of private seminaries. Now, when I read that Emma had gone to a seminary I thought it was just some sort of religious type school but in the explanatory notes that came with the book I have it says this about those schools:
" private seminaries: there were numerous fashionable boarding-schools for girls, offering such subjects as French, English, drawing, music, deportment, and elocution, and helping their pupils toward more advantageous marriages that their parents might otherwise have accomplished."
I wonder if maybe Andrew and Abby sent Emma there hoping to get her ready for marriage? I guess they had no such plans for Lizzie.
The other thing I noticed was on pg. 22, Caroline Bingley writes a letter and starts it with " My dear Friend," I guess Lizzie wasn't the only one who back then used that way of starting letters. Maybe it was a rather common way for people to start a letter and not some odd thing Lizzie only did.
Btw, Mr. Darcy is such a pompous you know what
