What does Mrs.Hickock reveal about the way people have treated her?

From the text:

Once her anguish had subsided, Mrs. Hickock expressed a need to confide. "There's nobody much I can talk to," she told her companion. "I don't mean people haven't been kind, neighbors and all. And strangers, too - strangers have wrote letters to say they know how hard it must be and how sorry they are. Nobody's said a mean word, either to Walter or me. Not even here, where you might expect it. Everybody here has gone out of their way to be friendly.
