I want to know the answer to the following question:
Who hosted the party whre Chopin met George Sand?
All the background I'm provided with is that "Sand, in a letter to Grzymała of June 1838, admitted strong feelings for the composer and debated whether to abandon a current affair in order to begin a relationship with Chopin; she asked Grzymała to assess Chopin's relationship with Maria Wodzińska, without realising that the affair, at least from Maria's side, was over.". Is that enough to answer the question?
Answer: no
