The Old Grey Donkey, Eeyore, stood by himself in a thistly corner of the forest, his front feet well apart, his head on one side, and thought about things. Sometimes he thought sadly to himself, "Why?" and sometimes he thought, "Wherefore?" and sometimes he thought, "Inasmuch as which?"—and sometimes he didn't quite know what he was thinking about. So when Winnie-the-Pooh came stumping along, Eeyore was very glad to be able to stop thinking for a little, in order to say "How do you do?" in a gloomy manner to him. Which statement describes Eeyore's character based on the characterization in the excerpt?
