wheat, chocolate, sugar, nuts, strawberries, onions, lactose; all of the things that modulate a person's affect. i'm glad i'm not one of the people who are allergic to the aforementioned nouns.
bees, latex, codeine. (not me, again).
"informal allergies" that induce levels of anxiety and/or panic-avoidance include; certain co-workers, ironing, and cleaning the toilet. while a person may not die from contact with these, others may die due to associated frustration.
sore throats and stuffy noses indicate a cold. "but it's my allergies" [intense whining]. dirty oxygen and plants? unless you are swelling up to the size of an SUV, and emergency services are on their way due to anaphylaxis, trust me, it doesn't count. if youre not packing an epi pen, or sporting a chunky medic-alert bracelet or necklace you don't really mean it. i wear a dorky bracelet, i will DIE if have penicillin. that's an allergy.
