You are looking forward to a pleasant day!\n"}]}

Everybody is too busy to exchange pleasantries.\r\n\r\n\u0022Gee \u2026 Even the docs on \u0022ER\u0022 got a \u0027good morning\u0027,\u0022 you grumble under your breath as you pull up the chart of the latest admission.\n"}]}

I told my daughter it was nothing, but she called an ambulance anyway. I think she\u0027s overreacting,\u0022 Mr. Graham explains while forcing a smile.\n"}]}


{"ops":[{"insert":"\u0022Daisy is a great herding dog,\u0022 he begins. \u0022But she\u0027s been acting peculiar lately and about a week ago, she bit me.\r\n\r\n\u0022I know she didn\u0027t mean it. That dog\u0027s crazy about me. I\u0027ve never seen her act like that.\u0022 He shakes his head to underscore his bewilderment.\n"}]}

{"ops":[{"insert":"\u0022Mr. Graham, your dog \u2026 ,\u0022 you begin before he raises his hand to cut you off. \r\n\r\n\u0022Doctor, she\u0027s had her shots for the year. When the vet comes out to the farm to vaccinate the other animals, he always includes Daisy,\u0022 Mr. Graham says gazing around as if in search of the nearest exit.\n\n\u0022I mean, how has she been behaving since she bit you?\u0022, you probe further.\r\n\r\n\u0022She\u0027s not acting like herself,\u0022 Mr. Graham replies. \u0022She was hyperactive earlier but now she just retreats to a corner and wants to be left alone.\u0022\n"}]}

I am positive though that she\u0027s had her shots this year.\u0022\n"}]}
