Grace at home is letting your brother tell the story wrong without correcting every detail.

Correcting every detail is about being right, and letting the error stand is a gift that costs you nothing but accuracy. Your brother gets the year wrong, the order wrong, inflates his own part a little, and the table enjoys the story anyway. Stepping in buys you a technical win and spends something warmer. Most families have one person who cannot help it.

Let one wrong detail go completely this week at home. No eyebrow, no quiet correction afterward. See whether anybody was actually harmed by the inaccuracy.
