What happened on Christmas Day at Finch's Landing?

On Christmas Day, Atticus takes his children and Jack to Finch's Landing, a rambling old house in the country where Atticus's sister, Alexandra, and her husband live. There, Scout endures Francis, Alexandra's grandson, who had been dropped off at Finch's Landing for the holiday. Scout thinks Francis is the most "boring" child she has ever met. She also has to put up with the prim and proper Alexandra, who insists that Scout dress like a lady instead of wearing pants.
