Well, she hated the second Spanish class.  The teaching style doesn't work for her.  So we are negotiating, working out a compromise rather than quitting.   Learning about your own learning style, and how to navigate a class to get the most out of it even when the teaching may not work well for you, these are lessons I value for her waaaaaaaaaaay above simple Spanish.

Later she wondered if our compromise isn't letting her off too easy.  She felt a bit sheepish.  This tells me I'm on the right track.  I want her discovering her boundaries for stick-to-it-tiveness and quitting, defining them for herself.  That lesson is most valuable of all.  It applies later to boyfriends, jobs, bank accounts, and the hugest life decisions.  This lesson can not be learned through force.  If you are not free to choose, you are learning the lessons of oppression.  Lessons which shouldn't be especially pertinent to the average adult living and working in the United States.  Right?  Obvs.
