Growth sometimes looks like going to bed instead of arguing.

Some arguments exist only because everybody involved is exhausted. At one in the morning your judgment is worse, your patience is gone, and the same subject would take four calm minutes in daylight. Walking away then is not avoidance. It is knowing the conversation cannot go well at that hour with those versions of you.

When a disagreement heats up late, say you want to finish it tomorrow, and then actually finish it tomorrow. The second half matters. Going to bed only works when it is a pause rather than an escape.
