How far away did Patty move? It does sound a bit suspicious that Bridgett has shown up at your house. Maybe she did ditch her there as she decided she was too much trouble....like Samantha was. Good luck trapping her, but then that sets up another dilemma of 'what if' she abandoned her? If Bridgett's caught and brought back to her, then what next for her? Where (if she was abandoned) will she be dumped next?
