RE: He didn't expect us meeting.

Thank you and they only nip when they are agitated. For about a year at our old place, there was one that we called "Squirry" and she used to jump on my wife to search her pockets for nuts. She knew that my wife always kept nuts for her in a pocket, and when she found a nut then she would hang upside down on my wife's back to eat the nut. Here she was on my wife.

If she couldn't find a nut, then she would nip my wife with her teeth, but it was never serious.
So, I don't think the squirrels don't love you, as instead they !LUV you :))
