So I wrote a plagiarized story. I'm only in middle school. But my teacher wants me to show my parents the story and have them sign it. My parents take these things serious and I got scared thinking of what my parents would think?

Then I guess you learn a lesson ... Think about the consequences of your actions BEFORE you do something.

What concerns them more than anything is that you say "My parents take these things serious."

Why the heck don't you take it seriously?

Your present attitude does not bode well for any future success.
