So...my little gray friend actually greeted me at work this morning! lol He's part of a 'couple,' so I've decided to call them Oscar and Felix. He was right there when I pulled into my parking spot, and let me talk to him for quite a while. I knelt down with some corn...again, he put up another little paw, as if contemplating, but decided against it. I have faith he'll soften and warm up to me.
