Families across the Christian world are gathering for Christmas even now, with caravans of cars and planeloads of passengers headed to hearth and home. Christmas comes once again, filled with the joy, expectation, and sentiment of the season. It is a time for children, who fill homes with energy, excitement, and sheer joy. And it is a time for the aged, who cherish Christmas memories drawn from decades of Christmas celebrations. Even in an age of mobility, families do their best to gather as extended clans, drawn by the call of Christmas.
