Stayed home this morning doing computer work on the one wire Mars. Can't get it to read temperatures. Left at 11:30 to go to the 1 PM Rosenkavalier performance. Boy is it cold outside!!! We had to stand in the cold until they opened the theater doors. The performance was spectacular. The blending of female voices, especially when those voices are Rene Fleming and Susan Graham, is so spiritual and beautiful. Instead of dinner at home we went over to La Cocina because we didn't get out till 6 PM. We stopped by Trader Joe's and picked up wine for dinner but then decided to not eat at home since it was so late. We had Frozen Margaritas and Quesadillas, our usual dinner there.
