Does everybody have a dark side? I need to write 4 paragraphs and I don't know how to start.

Start by brain storming. Think of all of the people you've known or read about who have a dark side. If you can't think of any, then you may want to take the other point of view -- that most people do not have a dark side.

Once you've thoroughly thought about this question, write a tentative thesis statement. Outline the two or three ideas that support your thesis.

Then write your essay.
