Being an engineer, my flippant response would be that it'll be good for the kids to see how boring engineering is on a day to day basis. Why would you lie to the kids about your job experience? Do you want to trick them into suffering like you do out of spite or something? You could discuss how working in teams is pretty much the core concept of engineering and how you as a lone engineer can't do anything by yourself -- not even entertain high school kids.
