I haven't lost as much ability as I was afraid I would have. I can still get a pretty nice tone; my fingers have just lost the memory of where exactly the notes are, and how to shift precisely, so I tend to play out of tune. My left hand also has a tendency to collapse around the neck, which is a bad habit I had before that is just worse now. But I'm noticing it, so I can fix it. And I think I have the patience now to get it all back.
I love rediscovering pieces that I had forgotten about - turning the page, mentally playing the music, and going ooooh I remember this! I love this one!
Of course, I had to put Mithril outside while I played to avoid getting my ankles gnawed to death. Poor kitty. *stifles a laugh*
