Nobody knew exactly why Wanda sat in that seat, unless it was because she came all the way from Boggins Heights and her feet were usually caked with dry mud. But no one really thought much about Wanda Petronski, once she sat in the corner of the room.
 
     The time when they thought about Wanda was outside of school hours — at noon-time when they were coming back to school or in the morning early before school began, when groups of two or three, or even more, would be talking and laughing on their way to the school yard.
 
     Then, sometimes, they waited for Wanda — to have fun with her.
 
     The next day, Tuesday, Wanda was not in school, either. And nobody noticed her absence again.
Explanation:
 
The narrator then said that no one in the classroom knew why Wanda sat in the corner of the seat. She might have sat in the corner because she had travelled from Boggins Heights (an area where poor people live), and her feet were often covered in dried mud. However, after Wanda Petronski took a seat in the class's corner, nobody was concerned about her.

Wanda's classmates used to think of her when the class got over. They used to think about her during lunch break, morning time while coming to school and even before school began. Whenever her classmates (a group of two, three or more girls) came to school, they used to talk and laugh about her on their way to the schoolyard. Here, one can find that her classmates would make her fun until she arrived at school.
