Who was Wanda Petronski? What type of girl was she?

Wanda was a poor Polish immigrant girl. She was very quiet and reserved. She rarely said anything. She never laughed loudly. Sometimes she smiled with a twisted mouth. She used to go to school with American children. They made fun of Wanda because she claimed that she had a hundred dresses, though, in reality, she had one old faded dress. She used to wear the same dress every day to school and used to commute to school alone.
