One of my best friends is really allergic to peanuts and when we were little he'd only ever seen already shelled peanuts and so when he was at a birthday party, they were having not shelled peanuts and because he didn't know what they were, he ate them with the shell... His throat got so swollen that he couldn't breath and he nearly died...
It's really easy and fun to make peanut-less homemade "Reese's cups" using mini muffin liners, nut substitute, and much better chocolate than anything Hershey makes. I was obsessed with processed food as a kid too. I kind of can't believe how much better homemade tastes (and how much batter you get to eat in the process . . . for science).
once, my friend who is VERY allergic to pretty much everything, including nuts, was victim to a kid deciding it was a cool idea to smash a peanut butter sandwich in his face.
I have an really horrible peanut allergy, and this idiot tried to kill me by flinging peanut butter at me. The teacher got super angry at him, but the next year he smeared it all over my back back.
