To My Big Sister Red

To My Big Sister Red is a note $$ It is evident that this is a letter not written by Red Tourette's sister Lily, as she had already been killed. Several clues show the lack of authenticity, including the use of the nickname "Red" as well as the unusual closing name of "Lily" instead of "Lil."

Location
The note can be found in the federal ration stockpile, on the table in Red Tourette's room.
