Incidentally I visited a leopard at the Asheboro NC zoo once, and I did the slow blink at her. And she blinked back. I felt so hono(u)red.
I read with amsuement about how humans might communicate with aliens if we ever come into contact. Heck I communicate with an alien every day and we get on pretty well and I think we love each other. Sometimes when I appear to her to be stupid it’s because I know exactly what she wants but it’s not good for her. Try explaining that to an alien! So our communication is not perfect but our mutual love is. At the moment Amber the Red is legs in the air around the back of my laptop, scrabbling round the sides, having been frustrated at not being allowed to sit on my keyboard, which she does all the time when I forget to close the top down. I now have to get off my computer now she has appeared round both sides 6 times in the last two minutes!
