Just tell the truth, Patty. Considering how much you’re scarfing down at one whack, you’re obviously going to get sick yourself. At the same time it is YOUR CANDY and Charlie Brown never did ask nicely for it. He just demanded you fork it over. So tell him the truth. Tell him you don’t want to share with someone so rude as to not ask “Please gimme some candy?” and that he can go shove it.
