Do other parents have conversations like this?
"Do you want me to read you the synopsis of Act II of Goetterdammerung, or a baby book?"
"Act II of Goetterdammerung, then a baby book, Daddy!"
This came out of the fact that when I picked her up from school the other day, Act III of Siegfried was on Radio 3 and took her fancy (the bit where Brunnhilde wakes up and starts going "Heil dir Sonne, heil dir Tag chiz chiz" like some demented soppy girl in a Molesworth story). Anyway, I went to the bookshelves and found dusty and long-untouched copies of Ernest Newman's 'Wagner Nights' and a Wagner biography which had a synopsis of the Ring cycle, and started reading an act a night as part of the bedtime story session.
And yes, The Ring makes a great kids' story. My mind started wandering (just call me Der Wanderer...) and imagining what Beatrix Potter, Enid Blyton or Dr Seuss would have made of the plotline. Doubtless my attempts at extracts will follow at some point.
