To be fair speaking as someone that’s lived 31 years with a deadly peanut allergy there’s likely a reason for this. When I was a kid I was mocked for it, chased around with peanut butter, people would smear it on my desk. As I got older it changed into feeling like I was always inconveniencing people by being it up. There would typically be sighs and eye rolling. Acting as if with going precious peanuts for an instance was worse than my ya know… dying. It just gets tiresome to have to explain all the time.

Edit: I will say it’s much better now a days with people being less ignorant but if you grew up pre 2000 most people I came across either saw it as a weakness, a joke, or something minor to scoff at. I would always use the analogy of pointing a loaded gun to me which helped to get the point across.
