That almost happened to me, once. My DH & I had our girls in our arms in Petsmart, and a lady came up, and started talking to my tiny Kia, who I had in my arms and she tried to take her out of my arms, and I had her held, very snug, tightly in both arms against my chest and I said, "Excuse me???"
She hadn't said a word to either my DH or me.
What is with people these days????
