Today Alice showed me that she now understands CD trays, at least enough to open them and pull the CD out of the tray. She used to get them out by accident by randomly pawing the front of the computer, but today I saw her deliberately and with forethought press the button to open it. At least she’s acquiring important modern survival skills.
In other progress news, Alice can now navigate the stairs on her own not only up but now down as well (controlled descent, you hecklers! Not just tumbling!).
