Incorrect Information about Grieg's Impression of Tchaikovsky

The quote as referenced in the sources is: "He is melancholic almost to the point of madness. He is a beautiful and good person, but an unhappy person. I did not think the latter when I met him in his time, but so it is: either one has others or oneself to fight."

I think this makes it clear that Grieg did NOT find Tchaikovsky sad upon meeting him, but later after he had read about Tchaikovsky's life.
