What shall I write a short story about? :)

Answer 1

You can write about your self( How you look, What your hobbies are, What you like and dislike, and how you want to change you life in better way than it is now or what are something you need to add.) 

Answer 2

At a Chinese restaurant, your character opens his fortune cookie and reads the following message: "Your life is in danger. Say nothing to anyone. You must leave the city immediately and never return. Repeat: say nothing."...
Or... At the airport, a stranger offers your character money to carry a mysterious package onto the plane. The stranger assures your character that it's nothing illegal and points out that it has already been through the security check. Your character has serious doubts, but needs the money, and therefore agrees...
Or... A man elbows your character in a crowd. After he is gone, she discovers her cell phone is too. She calls her own number, and the man answers. She explains that the cell phone has personal information on it and asks the man to send it back to her. He hangs up. Instead of going to the police, your character decides to take matters into her own hands...
