Maybe some people got sick, but what I saw was people applauding the effects. When the helicopter zombie stood up, people applauded. When a guy gets the top of his head lopped off, are they applauding that some horrible thing happened to a person, or are they applauding how it was technically pulled off in a realistic way?
My children were taught at an early age how money works and that it comes from hard work. They've been on a commission - not an allowance - since they were little. They learned that if they worked around the house, they got paid. If they didn't work, they didn't get paid.
