-I love that saying "He wants to have his cake and eat it too." It's used to describe someone who is over demanding but I feel like that saying doesn't do a good job of conveying that. If someone is given cake and then wants to eat it I don't think of them as being irrational. Has anyone ever been okay just with having cake? "You mean you want cake and you want to eat it also?! You are a maniac. That's not how the world works dude." "This guy just wants to have it all, he wants to buy a house and then move into it. He wants to buy food in a restaurant and then put it in his mouth. He wants to install a toilet and then urinate into it."
