Today was recital day. Youngest Son sang "Wisconsin State of Mind" by Billy Joel and himself, Youngest Daughter sang a German song about Gretchen at the Spinning Wheel, and Oldest Son sang "I've Got a Little List." All sang well, though Youngest Daughter adamantly refused to let me "film" her. What do you call it when you use a digital camera?

Today's opera is The Barber of Seville. Youngest Daughter likes opera, and came in to hear it when I turned it on, and was last seen fast asleep on the sofa. I wonder how much she can absorb that way...
