The concept of sharing does not seem to be coming naturally to Nestor. I cut up an apple for him, he eats a few slices and then, ever so generously, offers a slice to me (read: shoves it into my mouth). The expression of satisfaction upon completing such a complex task is very quickly replaced by that of utter despair when he realises that the apple slice is disappearing, forever. This is usually accompanied by an ear-piercing: “Neeeeee!!! Apppppeeeel!”
