The theme of the story is "an apology". I want to write a story based on what really happened to me. I was really arrogant and sarcastic in high school to everyone. Finally apologised to someone I was sarcastic to. She forgave me but kept her distance. Would it be ok if I submit a story for a competition based on that? I will change it to the protagonist bullying someone for years in the past, finally apologising, and coming to terms how it is too late for form a friendship. I am worried about moral and privacy issues.
