1. Thereās nothing about the kid having a gluten allergy. If the kid had an allergic reaction to gluten, heād be going to a hospital in an ambulance rather than being picked up by his parents. So it has nothing to do with people who have legitimate anaphylactic reactions to gluten.
2. The parents are so soft and scared of everything, they dress in multiple layers of bubble wrap. Their kid isnāt allergic to gluten, but heās having a mental breakdown to the point of needing to be taken home by his parents due to ingesting normal bread after his parents have convinced him of the evils of gluten. Theyāre making him as soft and anxiety ridden as they are. Itās a comment on a troublingly significant subset of parents and children in current American society.
3. If you got it without the lengthy explanation maybe itās humorous, maybe not. Thatās subjective and not arguing that point. Regardless, if it has to be explained to this degree, itās not humorous. š«¤
