Mine has a plate but puts it on table and eats dropping crumbs in his lap, then floor. He puts things away then asks where I've put them, swears blind it's me. If I put something of his anywhere I make him put down whatever gadget he's playing with, tell him to look at me, then tell him where I'm putting object. I tell him things, he swears blind I didn't,. I have now taught him to say when he says I haven't told him something and I know I have "I wasn't listening". Usually said with such innocence that I have to laugh. You've guessed I'm a bit of an ogre!
