Trudy said she'd like to try knitting again, though it was frusterating last time, six years ago. She said it's supposed to be good for your mind. It would be good if you could re-knit your mind if you noticed it unraveling. Probably knot, but it could be good anyway to try, if you don't get too fustrated. Cats are sure good for your mind, in both relaxing and stimulating ways.
