I usually end up calling mine sweetie pie or some such. But I do the stupidest thing. I sing "Miss Curly Mac, Mac, Mac, all dressed in black, black, black. With silver butttons, buttons, buttons, all down her...
and then Jack will say head, head, head cuz her head turned silver lol.
Well
She used to be almost completely black and she seems to like when I sing that hahaha. K, yes, I'm dumb.
