On Christmas morning in Canada, Celeste wakes before Perry and their twin boys. The boys had struggled to fall asleep the night before because they were excited about Santa finding them abroad, but Perry's firm command finally brought sudden silence and sleep.

Celeste looks out over a frozen lake, snow, and a lit Christmas tree, savoring the beauty of the holiday. She imagines the day ahead: presents, pancakes, playing in the snow, a snowman, a sleigh ride, and Perry posting cheerful family photos on Facebook.

Celeste reflects on Perry's warmth and his talent for giving thoughtful gifts, remembering that his joy in giving helped make her want to marry him. She tells herself the day will be perfect and that the family's happiness is real.

That certainty turns uneasy when Celeste thinks there is no need to leave Perry until the boys finish high school. She has already imagined ending the marriage when the boys complete their final exams, revealing that the ideal family image conceals serious private doubts.

In a later witness-style comment, Gabrielle challenges the public belief that Celeste and Perry have a perfect marriage. She recalls seeing them in their car on trivia night, dressed in costume, staring ahead in silence and not looking at each other.
