(A) Mark’s brother, Reuben, got a new coat, so Mom decided to make Mark’s winter coat out of Reuben’s old one. She took it apart carefully, cleaned and brushed the pieces and soon there was a nice new coat for Mark. He liked the coat very much, but he did want new buttons on it. But Mom said, “These are good buttons and look fine just as they did on Reuben’s coat.” He protested but when Mom had her mind made up, there was no point in wasting time trying to change it.
(B) Several days passed after the incident, and the family was ready for a trip to town. Of course Mark was wearing his new coat, and as he walked in front of Nellie, (a) she reached out again and butted him with her head. This time, Nellie was chewing on one of his coat buttons. “What’s the matter with that horse? Mark, have you been teasing her?” asked Mom. “No, I haven’t,” he said.
(C) One evening Mom said to Mark, “Put on your coat and run out to the barn. Ask Dad to bring some eggs.” He had been a frequent visitor to the barn, but the animals never paid much attention to him. This evening, however, was different. Just outside the barn door stood Nellie, their family horse. Before he could enter, (b) she banged her head against his stomach, and he sat down hard. Reuben and Dad came running when they heard Mark scream. Reuben said to Dad, “Whatever got into that horse?” “I guess Mark startled (c) her,” replied Dad.
(D) Reuben came up with the answer. He said, “Nellie only goes after Mark when he has that coat on. I think Nellie remembers those buttons when they were on my coat. I trained (d) her to shake the front of my coat to get sugar. I think that’s what she wants.” Mom was doubtful, though. However, when Nellie continued to make life miserable for Mark whenever he wore that coat, (e) she began to change her mind. Finally one day she said, “I believe Reuben is right. Maybe I’d better change the buttons.” So Mark’s wish came true after all.
