Whenever you say anything to anyone the other person always knows exactly what your thinking is behind what you are saying.

That would make it nearly impossible to lie, cheat or deceive others, even for the smallest thing.

So that way when your girlfriend asks you if you would still love her if she were a worm, even though you would say, "Of course my love!" She would know you actually mean "what the fuck are you talking about?" And you would know she actually meant "my emotional batteries are running dry and I want you to recharge them"
