In a strong marriage, a long marriage much cannot be said, should not be said. The spots on one's skin will be wisely ignored. Differences of opinion are tolerated, not debated.
Your memories may disappoint your partner as not those she has selected, refracted. Over dinner for two at the Mill on the Floss it could be dangerous to compare wills, losses.
Or it might result in belly laughs, Shakespearean revelations, the night he got us lost in the woods or she peed her pants at a party. The marriage was Faustian, in a good way, like going to a job in the Garden of Eden.
Having survived 25 years, knowing 50's impossible, what else do we know? Raised 2 boys, painted 3 houses.
