What should I write a short story about?

Give me some ideas. I've already written about disacceptance, bigotry, the dangers of meeting someone over the internet though I'm a hypocrite with that one, suicide, I have a few suicide ones actually, murder, and sci fi which also had to do with bigotry. I have an idea for one right now but I want to write a few and put my best together in a book so some ideas?
