The Kardashian sisters treat their mom BADLY?

I'm watching the latest episode of the Kardashian show and I'm really starting to see how badly these spoiled brats treat their mother, Kris. Khloe has a nasty tone to her voice toward Kris, whenever she is upset with her mom. Kim is up on a pedastel and thinks her sh*t don't stink. And Kourtney has a downright nasty attitude. Yeah, I understand that she was frustrated that Kris forgot her photoshoot but geez, there is something called FORGIVENESS. This episode has made their likeability factor drop in my opinion. I am not a big fan of theirs to begin with but this made it worse.
