What can I cook these fussy adult eaters?

You cook for what the majority can eat, the rest can bring their own food. You're not a restaurant where people have the right to order specialized meals! You tell them to feel free to partake of what is put out or bring their own and heat it up there if necessary.

As far as I'm concerned it's not the hostesses job to support cranky eaters and people who specifically won't eat this or that when they darn well could.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
