For years we could not see eye to eye about grilled chicken versus schnitzel. After extensive (and expensive) therapy, we worked out a supper schedule in which we compromised. On alternate weeks, we have the schnitzel my wife prefers with the side of my choice, or my grilled chicken with the side of her choice.
This worked reasonably well for years, but then one week we had a Bar Mitzvah on a grilled chicken night, which upset the balance. We are currently in late stage negotiations about how to recalibrate.
