By four in the afternoon most people are running on less than they think. Blood sugar down, three unresolved things from the morning, a battery at eleven per cent.
That is the version of you that gets tested. The nine a.m. self is considerate almost without effort. The four p.m. self has to decide.
Being considerate at all times is therefore not a claim about temperament. It is about the hours when the supply runs low, which is exactly when small courtesies get dropped, and also when they land hardest on whoever is in front of you.
