We need a "Jump to Conclusions Mat"

Well, to be fair, that isn't really sound logic. You need to reverse the conclusion and use that as your premise, thereby constructing a contrapositive, to make a statement with a reversed conclusion. As such, "if you don't take the game over to their house it wouldn't be free to play" is what you'd wind up with, and even that could be incorrect (So even our premise isn't airtight). If we allowed such callous abuses of the system, this would be a valid conclusion: "If it is raining, the sidewalk is wet. Therefore, if it isn't raining, the sidewalk isn't wet." This is untrue, because other things can make the sidewalk wet. The contrapositive to be found is "If the sidewalk isn't wet, then it isn't raining." Alright, I admit, I just wanted to talk about logic for a bit; you got me.
