Read somewhere this week about a game called "humiliation" in which you confess to famous classics you haven't read or finished. That got me thinking about my cultural blindspots in general.
Mine's opera. I just don't get it or like what I've heard. That makes me sound like a real philistine, especially as DH's father sang for the ROH.
And my cultural shame would be - chick lit. At the moment, one of my greatest pleasures is to have an hour to myself with a glass of wine and a trashy novel in which the heroine struggles, but always gets her man.
