The fact that a story makes you comfortable does not make it complete.

Comfort is a poor test of accuracy, and the mind uses it constantly. An account that leaves you blameless, or that explains a difficult person as simply difficult, settles quickly and stops being examined. Meanwhile the parts that would cost you something stay outside the frame, and the story feels finished mainly because nothing in it hurts.

When an explanation lands too easily, ask what it lets you avoid. Look for the version in which you played some part, and see whether it fits the facts. You do not have to adopt the harsher story, only to check that you did not pick the other one for its softness.
