Give people the benefit of the doubt once. Most of them are having a worse day than you know.
GRATITUDE
GRATITUDE
People rarely explain what they are carrying, so the short answer, the ignored message, or the sudden snap arrives with no context attached. Your brain fills that gap with a story in which it was about you. Usually it was not. One round of good faith costs almost nothing and turns out to be right far more often than the alternative.
Give one person a pass this week without telling them you did. If the same thing happens again, take the information seriously, because the rule is once and not forever. And on the day you are the one snapping, remember somebody quietly did the same for you.
Who snapped at you recently while carrying something you could not see?
Free, with nothing to buy inside it.
