You mean you don't have a list of invented 'allergies' as long as your arm, and a screwy diet which means you can't eat anything normal people would cook for you? That's definitely not the DUmmy way.
I have no food "allergies" myself, but damn, there are some things I just will not touch.
Such aversions don't appear to be a matter of taste--a great many things I don't like have a lot of sugar or chemicals or grease in them--but just simply the body (rather than the brain) instinctively saying "no, it's not good."
Usually, generally, most of the time, no one serving me as host or hostess has to go out of his or her way for me; I just pick-and-choose from what's offered, even if it's just a whole-wheat roll with real butter, and coffee, while everybody else is dining on six or seven different dishes.
That's not the problem--that I nibble while others are chowing down; temporary deprivation doesn't harm anyone.
The problem comes when others some times--not all the time, but some times--insist that I
must try this or that. That is where physics comes into work; an irresistible force meeting an immoveable object. This object remains steadfastly unmoved, but it's a titanic, epic, thing to see.
As for concerns about whether or not I'm "enjoying" myself, I'm there for the social company, not for the food. Food, I can get myself. And on the Head of St. John the Baptist, that's the utter truth. Food, I can get myself.
