I think this topic is interesting also.
The main reason it caught my eye is because of the drastic measures being taken in schools regarding *food* allergies.
Earlier this year I volunteered to teach several classes for high interest/career exploration day at our local elementary school - I was teaching kids about architecture and plants. Before I was allowed to teach the kids, I was given an information sheet that John Doe in 2nd Grade has a peanut allergy, and Jane Doe in 5th grade has a shellfish allergy, and I had to sign the sheet acknowledging my understanding. I was informed, in writing, that under no circumstances could I bring peanuts or peanut butter into the school for my own lunch. (Well, fine, I prefer hummus anyway). It was pretty obnoxious, and since I don't have kids of my own I was pretty surprised how adamant they were and how strong the language was.
So.... while our public schools are going to crazy lengths to ban peanuts, while concurrently becoming more permissive of service/working dogs on school property, the juxtaposition interests me.
I've never met a peanut butter sandwich that jumped up and endangered a bystander, but I have met children that are terrified of dogs. Interesting debate, I'm not sure what my opinion is.
