The detail outside the main event may explain why the event matters.

The centre of an occasion often explains itself least. Why a day mattered is usually stored at the edges, in who drove there, what got said in the kitchen, which person came despite something difficult. Ceremonies are designed and edges are not, which is much of why the edges are more honest.

At the next occasion you attend, give the margins as much attention as the middle. Note who is doing the work, who travelled far, what happened just beforehand. Those are the details you will want later, when you try to say why it mattered.
