This game is pretty simple, one user states something that happened to them, either fake or real, and the user below him tells him something he forgot to mention. For example: Player 1: I got a cookie
Player 2: What you failed to mention is that it was a super-cookie brought by aliens. I aced a test.
What you failed to mention is that you're good for a few people, and bad to other people! (think of it, everything you do can be good for you or other people, but bad for other group of people!)
