I wished both guards and prisoners 'Season's Greetings'. I don't understand Christianity, but I went to chapel anyway. There I saw real women, genuine smiles, wholesome love, and heard great singing. On the day after Christmas when the morning buzzer sounds, the prisoner may react exactly the opposite. He might spit on a guard or curse fellow prisoners.
Some prisons have boxing rings in their gymnasium while in others boxing is strictly forbidden.
So it's difficult to describe Christmas Day in prison.
