I want to know the answer to the following question:
What did Frédéric write parodies of in his letters?
All the background I'm provided with is that "His letters home from Szafarnia (to which he gave the title "The Szafarnia Courier"), written in a very modern and lively Polish, amused his family with their spoofing of the Warsaw newspapers and demonstrated the youngster's literary gift.". Is that enough to answer the question?
Answer: yes
