One of my clients runs a food education program in local schools to teach kids about where food comes from, how it gets to them and the benefits of eating locally. I was talking with their program coordinator and he passed on that he sometimes got funny answers to his written questionnaire. His favorite was:
Question: "Where do you think food comes from?"
Answer: "Pants"
Either the kid left out an "L" in his answer or he has a unique view on how things work.
In theory, there is no difference between theory and practice. But in practice, there is.
