It sounds to me that it's the 1% syndrome. A successful marriage is not 50/50, it is 51/49, and these 2 young Love Birds are still fighting over that 1%. Yes I've been married a few times, so what.
"2 young Love Birds are still fighting over that 1%."
Looks like 2% to me.
But I agree with you. All that stuff should have been worked out before they got married, however, in those love spats.
