Persons with special diets and those with regligous restricted diets are
not wackoos, nor are they necessariy full of anything, they have a
preference and that is okay.

If you enjoy this persons company, and want them to attend, just tell
tem what you plan to serve, and if that is a probablem, tell them it is
ok to bring dishes that they can eat.If they forget to do that,then it
really is no longer your problem.

You might be concerned, if they forget to bring their food,is there an
underlying problem, are they elderly,do they have alsthimers? If so,
don't make a big deal, there are always tossed salads, or fruit salads
to give them.

This is a day the Lord has made,lets rejoice and be glad in it.
