Dead people

My friend, the nun, drove with her little nephew past a cemetery where somebody was being buried. My friend explained to her nephew that we all had to die that is how we go to heaven. He promptly wanted to know "if God then dug us up." She assured him that God did not dig us up but that our soul which was like a ghost flew to heaven. He turned to her and very determined told her that only birds could fly. "Everyone knows that." At that point she knew she was getting way ahead of him and changed the subject.
