I was once shocked to read on the bottom of a sensitive piece of writing about a personal experience :“ This work is terrible! There are far too many spelling errors and your writing is illegible .” It might have been a sharp criticism of the pupil’s technical abilities in writing, but it was also a sad reflection on the teacher who had neglected to read the essay, which contained some beautiful expressions of the child’s deep feelings. The teacher was not wrong to draw attention to the errors, but if his priorities had centered on the child’s ideas, an expression of his disappointment with the presentation would have given the pupil more motivation to seek improvement.The author’s attitude towards what the teacher did is ________.

A. approving
B. positive
C. critical
D. indifferent
