Okay so, when you're in a game, and you push someone on purpose, you get a yellow card, which means you get a penalty and there's one less player on the field. I think it's only fair if the player pushes you, and doesn't get called on it, you should be allowed to push them back, without getting a yellow card. What I also think would be fair is, if the player on the other team is saying stuff to you, without the referee hearing, you should also be allowed then, to push them. I personally think we should revise the rules of soccer.
