Horrifying

"Good afternoon, Mrs Butterworth. This girl Sarah is not supposed to be in my class. She is better and should be where her mates are. She should be in class three." The teacher sputtered enthusiastically with her right hand placed on the shoulder of the little girl when they walked into the office of the principal. 

"What do you mean by that? She is just starting school and have no primary knowledge of A, B, C. Please go now, I am busy." The principal rumbled and did not even lift her head to look at them but kept writing on the file in front of her with a blue pen.
