DH and I agreed many years ago that WE ARE ONLY ALLOWED TO MOAN ABOUT THINGS WE CANNOT CHANGE ON WEDNESDAYS!
It started as a joke, but we soon found out that it did our mental health a world of good, so we stuck to the rule.
No going on and on about the government, the weather, the price of petrol, inflation and the like.
If it is not Wednesday: SHUT UP. If it is Wednesday, a moan is permitted, but ends when the other asks, "What do you intend to do about it? Get on your knees and pray for less rain?" or simply says, "Get off your backside and do something to change the things you can change!"
