Glenn Beck discussed this briefly and the peanut allergic kids would have to eat acorns to (possibly) be affected. What kid is going to eat acorns which are very astringent, taste awful?
I brought in a PB&J one time (before I knew about his allergy). He stopped by my cube on his way out the door, asked me to step outside, explained his issue, and (politely) asked me to refrain from PB again. As his eyes were already all red and puffy, and he was obviously in some, albeit slight, respiratory distress, I said "sure". Brought Ham, Tuna, etc....no more PB, and no more problems. Up until then, I would have agreed with Beck...figured that you had to eat the stuff to have an issue. So does this lady have a point? Maybe. But if her daughter is allergic enough to have a severe reaction to something as common as an oak, she'll need to learn (quickly) to adapt to it.....rather than asking the entire world to adapt to her.
