Watch how you act when you’re tired and hungry. That’s the unedited version of you.

Politeness runs on energy, and when the energy is gone, whatever is underneath becomes visible. The snap at a sibling, the two-word reply, the sudden certainty that everyone is against you: that is not your whole character, but it does show which reactions sit closest to the surface. Knowing your own low-battery behavior beats pretending it does not exist. It shows up at roughly the same points every week.

For a few days, mark when you felt worst and what you said in the hour afterward. Look for the pattern, not the guilt. Then eat something and take the hard conversation later.
