Gear-grinding update - Mom called Cousin today and offered to let Cousin's dog (now referred to as CD) stay with us. Apparently CD has been tearing up cousin's apartment pretty badly. So mom prattles on about how CD has always had a packmate and how our dogs are her pack and blah blah blah. And I said, "So Cousin's actions finally bit her in the butt and you jumped in to save her from them?"
She got really quiet. "I didn't think of it that way."
