I forgot to mention this, but on Tuesday, our neighbors were starting up their lawnmower for the first time of the season. When they got it going, it sort of put-putted for awhile before it got up to speed. While it was put-putting, I looked over at Nora and she was doing a little dance to the beat of the put-puts. She was just bouncing up and down with her feet on the ground, and she had a look on her face of total satisfaction (like, "Yeah. That's it"). It was quite a sight to see.
Currently, she's dancing to the ring tones on the spare cell phone that I've given her.
