Follow the Leader

We have an unspoken truce. She still hisses and growls for show when I get within 3 feet, and sometimes I just plop down there to antagonize her. She remains intrigued by me and my habits. If I sit on the window sill, then she has to try it when I leave. If I go to the sink for a drink, she jumps up there as well when I'm done, but she remains confused because she doesn't know the technique for drinking. I'd be happy to teach her if she could only get over the hissing thing.
