When I was in 6, I learned that a classmate at school was allergic to some food or another (peanuts, I think) but I didn't know what an allergy was. I asked and was told that "if you're allergic to something it means you can't eat that food."
Well, I HATED stewed squash, so I told everyone that I was allergic to squash because I thought that was what "allergic" meant. People were horrified when they found out that my parents made me eat my squash even though I was"allergic to it." Now I like stewed squash and eat it with no ill effects.
