What a load of bollocks.

- If you don't like the person don't help, don't talk, walk away. Save your time.

- If you are not going to execute the idea give it to someone else so at least you'll help the world to be a better place (assuming you are not working on efficiency of drug smuggling)

- If you are going to do the idea yourself you don't say it to anyone, obviously!

- If you like the person and if you are not going to do the idea by yourself and still refuse the share ideas. "What's your problem?"
