It's not always about malice, actually, it's just that few people who don't suffer from allergies can really realize or believe what a kind of dangers allergic people encounter everyday. If you've been eating peanut butter all your life, it would be hard to believe that I might die after having just one bite. And sometimes people just don't believe that things are that bad, and it concerns adults as well as children. I can give an example. My mother has a terrible allergy to soy and soy products, it's just as strong as my nut allergy is. So, once when we were on a picnic with some of our friends, several years ago, one woman gave my mother some soy sausages, NOT telling her that this was soy. She meant no harm. She just didn't believe my mother was really allergic, so she thought she could demonstrate that soy's all right. Needless to say, my mother found that plot out after just one bite :x And that was a grown up, clever woman, a prominent member of her church... What to expect of small kids?
