I imagine that there will be little talking because Yosef will be giving a big speak or lesson. Sure, he did not post on the forum even once, and never gave some money to guardyoureyes.com, but I think he would still be at the head of the table.
It will be interesting to see how many of his children are at the table. Will their be a lot because it is the job of Yosef, and therefor his children, to resist these temptations? Maybe there will be very few because his reward for passing his trial was that his children would have special protection from similar trials. I think it will be the former.
No matter what though, I just hope we are served cake with lots of frosting on it.
