You have a point there.
Another possibility is that, since the allergen changes, then becomes extremely popular, then is replaced by a different allergen, is that it is media-driven and not biological at all. It also is a way of demanding attention from others. (I am sure that some allergies are real and are dealt with appropriately by their sufferers, but that is not what I am referring to)
Years ago, I attended my M-I-L’s Passover Seder, attended also by a Vegetarian cousin. The meal was served “Family Style” which meant that one could take whatever foods one wanted from big dishes in the middle of the table.
Cousin M was not content to merely serve herself vegetables and enjoy the meal. She would loudly snort with disgust and avert her nose as the meats were passed around. That was followed by a pontificating lecture against “cruelty”. Needless to say, the Haggadah was not read in its entirety, nor were any songs sung, because Cousin M had diverted ALL the attention to her SELF.
You are so right about that-and my mind goes right to those otherwise invisible parents who want their kid’s whole school to be peanutless brcause their little darling might get a whiff and expire. I say let the kid be homeschooled or wear a hazmat suit to school-it isn’t anyone else’s problem.
Or, how about the mediocre, previously unnoticed office drone who wants a perfumeless/deoderantless office, lest they expire from a whiff? It is the allergy du jour...
