Do the Npc′s talk with eachother?? i never noticed any real dialogues between them!
i mean in Oblivion the Conversations werent the Best ones but at least they talked with each other and made a real life there but in skyrim i dont see anything like that....

Yes they do all the time. I can't walk five feet without it happening lol.

they talk to eachother alot.
mostly it is nazeem moaning at others.

Nazeem: "Do you have anything even remotely fresh?"
Anoriath: "I can assure you, it's all fresh. I hunt the game myself, every day."
Nazeem: "Hmm. As you say."
Anoriath: "Maybe you'd like to try the horker? Or some beef?"
Nazeem: "You don't prepare the meat with any of those strange Elven spices, do you?"
Anoriath: "Ahhhh... No, no Elven spices. Just some salt, to preserve it. You're not afraid of salt, are you?"
Nazeem: "I'm not "afraid" of anything. I simply prefer quality merchandise. No, no this meat won't do at all. Too much fat, and it all smells... wrong."
Anoriath: "Suit yourself, then. The woods are that way. Outside the walls, walk straight ahead. Can't miss them. Good luck on your hunt."
Nazeem: "Good day."

exactly

have you heard him speaking to ysolda and carlotta.

Indeed. I like to use the console to steal his wife just as a [censored] you xD

hahaha

i murder her all the time then i steal from the farm, after that i kill him with my fists.

Eh that just seems to fleeting of a punishment. I like those who annoy me to suffer greatly.
