The vows become practical when the guests leave and ordinary disagreements return.

Promises made in front of people are easy in the moment and difficult in practice, and the difficulty is made of small things. Not grand tests of loyalty but who apologises first, who handles the tedious call, whether you stay decent during an argument about nothing. The ceremony states the intention; the ordinary week is where it either holds or does not. Nobody watches that part, which is what makes it the real one.

Pick the least dramatic commitment you have made to someone and check how it is doing this week. Then keep it once, in a small way, at a moment when it is inconvenient.
