Now Sandy and Vollbracht are back together again and pleasing the crowds with their daily shows of affection. For Vollbracht, who has a wife and two children of his own to worry about, it's a bittersweet reunion. "It's nice for the zoo and to be followed around again," he says, "but I can't stay her partner forever." But finding her someone else might not be so easy, either. "We can't find her a partner," Vollbracht says. "She chooses, and it's her decision or nothing."
