Mrs. White lost her dog. After searching place after place, she placed a “Lost Dog” advertisement in the local newspaper.
The following morning her phone rang and a       voice began, “I’m calling about your   __  .” Then the caller coughed and cleared her voice a few times. She       that she wasn’t feeling well and that, in fact, she hadn’t felt well       her husband died three years ago. She went on to tell that her parents had passed away, and her sister was       with a deadly illness. Even her friends were not doing well.
