So very wrong, you were!
On the bright side, I took these pictures with my new camera so I was able to maintain a relatively safe distance. On the down side, I think I still managed to piss her off because after a couple of minutes of invading her space she scrambled up underneath the porch rail, presumably to plot my demise and eventual consumption. So I guess that means that use of the front door (necessitating crossing into Her territory) is off limits, at least until the first frost. But maybe I’ll not take any chances and just wait things out until spring.
