Like the title says, two players engage in mostly quiet small talk amongst themselves. However, they miss what the other characters are saying, both to the DM and to each other, meaning either I or the player then has to reiterate everything that just happened.
The other players are great. They listen to everyone and RP when applicable, but the "problem two" have formed a bond and just love to giggle and talk AS SOON as someone other than one of the two of them starts talking.
I'm looking for ideas on how to change this. It's a game where everyone should feel involved. I realize a roster change is an option, but it's my last resort. We all started together, and I don't want to go that path if I can avoid it. I've also tried adjusting the seating arrangements with no luck.
One of my players is unhappy, as am I as DM, and one of my ex players won't return due to this. Not paying attention, what's the point of roleplaying your character if only the DM hears you? Or for that matter, pulling off some sweet move to a bad guy? Whats even the point of being there if you're ignored?
Any ideas or suggestions is helpful.
