The corner where Wanda sat was occupied by the rough boys who did not make good marks. It was always noisy because of the dragging movements of the feet on the floor. The roars of laughter could be heard when anything funny was said. The floor was always dirty with mud.

Wanda sat in the seat next to the last seat in the last row in Room Thirteen. 

Wanda sat in that corner because she came all the way from Boggins Heights and her feet were usually caked with dry mud.

The corner of the room where she sat was occupied by the rough boys who did not make good marks. Everytime, the corner was noisy because of dragging movements of the feet on the ground. Most of the times roars of laughter were heard when anything funny was said. The corner was usually dirty.

No, Wanda didn't sit in the corner because of being rough and noisy. Instead, she was very quiet girl who rarely said anything at all. Nobody had ever heard her laugh out loud. She had to sit there because her feet were usually caked with dry mud and the corner of the room was usually dirty with mud.
