I understand that it’s not “normal” to be revolted by mayonnaise. But that didn’t stop me from groaning when I watched my roommate glop a spoonful into a bowl of tuna. God, I really don’t like tuna either. Rationally, I know that tuna with mayo is something that people eat, but I don’t want anything to do with it. My aversion to mayonnaise began when I worked at a coffee shop in high school. One of my duties as barista/sandwich maker was to “flip the deli.” That meant mixing all the fixings, which included a giant vat of mayonnaise that had been coagulating for hours. Did you know that it starts to get a brown crust on top when it’s “tired”? Argh! I can’t go on. My point being that all of us have strange repulsions.
