Chekhov is one of the best short story writers I know. His prose is beautiful but it's his characters that are unforgettable.
But this story, I believe, will not stay in my memory because of some characters. Oh, no. This is going to be remembered mostly as "that story that is depressing as hell". Not that I haven't read realistic fiction before or more tragic tales than his. I just didn't expect that Ksenia will get nothing for her cruelty. Plus, it wasn't just a story about one family this one is a bit deeper that that, and in short "life sucks and only in fairy tales everyone gets what they deserve"
