Mary: "Hi, can I help you?"
Ms. Daughter: "Yeah, my Mom, Ida Behere, has an appointment with Dr. Grumpy today, and so I was coming to join her."
Mary: "Okay, but her appointment was over an hour ago. She's already done, and has left."
Ms. Daughter: "HOW COULD SHE DO THAT TO ME?!!!"
Mary: "I"m sorry. Maybe you should drive in with her next time?"
Ms. Daughter: "I demand you call my mother immediately and get her back here to repeat the appointment!"
