In 2026, make "peace".
"to make peace": to forgive (each other), to be friends again, to end a quarrel.
Pick a falling-out.
Remember that "making peace" is neither apologising nor being forgiven. It's recognising that the world is a better place with two fewer people at odds.
Then all it takes is being a "grown-up", man or woman, taking the helm, and dealing with it.
As always, and as with everything, books help. To understand why it matters. To move from words to deeds.
