On Saturday after mass, father was sitting on the table talking to people and I asked him, Father do you know that Chicago cub fans can't go to heaven? He just laughed and I was certainly wrong since he is most assurdely with God now. We will miss him very much. I was lucky to visit him just six days before he died.
