I'm getting such a kick out of this series. Last night the character played by Judi Dench was deciding how to earn some extra money. When a school was suggested, she started riffing about all of the subjects she wouldn't be comfortable teaching, nixing arithmetic, the globe ("the notion that the world is round makes me feel quite giddy!") etc etc. finally settling on the idea of opening a tea shop, which suited since she was opposed to handling "sticky" merchandise.
Okay, maybe you have to be as geeky as me to appreciate it, but the portrait of this nervous little town in 1840 cracks me up, and is touching at surprising moments.
