I get what the advert is TRYING to do, that doesn't need explaining.
People are a bit sad clearing Christmas away, as a majority of people are ( not everyone but adverts have to appeal to the highest %), Dad finds record, memories evoked, hugs and tears. Fin.
Problem is, this could be quite triggering to some, as the sadness of Chrimbo being over looks like something genuinely awful has happened, the family is TOO sad, on the point of looking scared.
And why did the son not point out to the Father on Christmas Day that he hadn't opened his present from him? that spoils the narrative as well.
If my child buys me a thoughtful gift, they would be waiting on pins for me to open it.
A few tweaks ..maybe the family could exchange rueful looks whilst packing away, an arm round a shoulder etc. Maybe we could see the son rushing out to a record shop on Boxing Day with his Christmas money, then sliding the record under the tree?
It's a nearly -but- not- quite-there from me!
