The friend who believes your difficult day does not need a convincing performance of distress.

With some people you find yourself proving it: the tone, the details, the evidence that the day really was as bad as you said. That effort is exhausting on top of the day itself. A friend who simply takes your word removes a whole layer of work, and the difference is obvious immediately, because you stop editing while you speak.

Notice who you perform for and who you relax with, and spend more of the hard weeks with the second group. When someone tells you about their day, believe the first version rather than waiting for proof.
