Text:
The informant’s family opens all presents from non-immediate family on Christmas eve, while the presents from immediate family are saved for Christmas Day. On Christmas day these presents are only opened after the informant’s mother reads the Christmas story aloud.

Context:
The informant thinks that the presents of immediate family being saved for Christmas is because it’s more exciting to see people open gifts that you gave them and hear what they think than it is to see them open presents from other people, so it’s saving the most fun for the most special day. As for the Christmas story reading, he thinks that’s to prioritize and reinforce that it’s the celebration of Christianity and Jesus’ birth, not just a random holiday.

Analysis:
I think the informant is correct with all of his analysis, but that there is an extra layer to saving the immediate family’s presents for Christmas day, and that is to emphasize the importance of one’s family a little more than any other friends or relatives.
