Calvin's not talking to me. Usually when I give him a head rub (or barely stroke his head), he grinds his teeth, a bunny way of saying that they are very happy. Well, I got no grinding when I gave him the special "after ear cleaning" head rub, and I got none when I just petted him. In fact, he gave me the cold shoulder. I'll have to get into his good graces tomorrow night, for it's bed- and salad-time right now.
