Some people give you a choice: A or B. When you choose A, funny looks cross their faces. "We were hoping you'd pick B," they say. "Yes, well," you say, "I can understand that. But I still want A." "You should really pick B," they reply. And when you still choose A, they give you B. It turns out they: (1)Never had A to begin with (2) Want A for themselves (3) Were testing your maturity-level. Had you been mature, you would have picked B without any prompting. Too bad! You've just lost your power to choose. Maybe next year, when you're a little older, they'll give you choices again. (Those choices will be, of course, A or B.)
