Q1.5
I'm writing a book/article, and I'm reaping the net for stories and ideas. You don't mind if I steal yours, do you?

A1.5

Most people would like to maintain copyright over their stories (true or fiction), so you should definitely obtain permission from the original author before publishing a story for profit. It's OK to use someone's stories if you have written permission from the person and/or are paying them in some way. It might also be a nice idea to give a story for each one you take. Just a few things to think about.
