A couple weeks ago, a friend of mine came to Edinburgh for a visit and suggested that we watch Lena Dunham’s movie Catherine Called Birdy. She knew I’d enjoy the movie because a) it’s historical fiction b) it’s a comedy c ) it’s about sassy young ladies. She was right, of course. I did like the movie. But not just because it ticked all of those boxes. I liked the film because it was actually funny and warm and kind of quietly transgressive in a way I wasn’t expecting.
