When I take King (Molly doesn't really like to go) to see my mom in the assisted living place she's in, he will walk up to anyone with their back to him and touch his ice cold nose to their hand or elbow. If he knows them, he will do it to the back of their neck if I don't stop him. There was one old woman, gone now, that he was nuts about, and would climb up on the couch with her, and she would hug him with a death grip. He would close his eyes, and it was obvious he really enjoyed it. When I would come without him, she would always ask me how he was, and why didn't I bring him. About half the time, he would touch his nose to the back of her neck, startling her, but she didn't mind it really. Her sister who also lived there HATED King, and if he approached her, she would snarl, "Get him away from me!!". She claimed he was "Vicious and crazy". Seemed like that described her pretty well.
