I like to have a chat with house guests but I find it kind of sad that they are silent as soon as I stop talk to them.

I think if a player and or house guest comes into close range they should start talking as long as the player has granted them the permission.

It could mean a bit of coding but I don't think it is very complicated.

It does not need to be intelligeable but just some background chatter ... would add enormously to the atmosphere.

I mean we have some dialogues in cities between npcs. We could have something similar in our homes.
