IS IT MATRIMONY OR ACRIMONY?

I think it is a given that marriages are made between contrarian spirits, the wife always at the loggerheads with her husband, most of the time, in most of the marriages. May be it is to do with the fact that acrimony sounds like matrimony, don't know.

Well, as I said, I am reading "Nothing to be Frightened of", by Julian Barnes. Here's his grandparents:

"Grandpa, in his male armchair, deaf aid occasionally whistling and pipe making a hubble-bubble noise as he sucked on it, would shake his head over the Daily Express, which described to him a world whre truth and justice wre constantly imperilled by the Communist Threat. In here softer, female armchair- in the red corner - -Grandma would tut-tut aya over the Daily Worker, which described to her a world where truth and justice, in their updated versions, were constantly imperilled by Capitalism and Imperialism"

This gusty pair, not only reserved opposite positions for jousting about politics, but even found a way to make provision for future differences of opinions:

"My brother remembers ritual- never witnessed by me - which he called the Reading of the Diaries. Grandma and Grandpa each kept separate diaries, and of an evening would sometimes entertain themselves by reading out loud to one another what they had recorded on that very week several years previously. The entries were apparently of considerable banality but frequent disagreement. Grandpa: "Friday. Worked in garden. Planned potatoes." Grandma: "Nonsense. "Rained all day. Too wet to work in garden."
