Observation
Growing up, my cousin was (allegedly) allergic to more foods than not. Though, I’d never seen him have a reaction. One Thanksgiving, I took a speck of the cream cheese I’d schmeared over the hole of my bagel and rubbed it on my cousin’s neck undetected. Lo and behold, he had a rash five minutes later. Soon after, he ejected his dinner and went full tomato head. My memory goes fuzzy after that.
I’ve never fessed up to that. So, here I am, full frontal, half hoping my confession gets lost in the haystack.
