The appointment is one hour; preparing for it may occupy the whole morning.

An hour on the calendar can consume a morning. The travel, the paperwork, the waiting room, the nerves beforehand and the flatness afterward all belong to that appointment, though none of them appear next to it. People planning around someone else’s schedule see only the visible hour and wonder why so little else got done.

Count the whole shape of the thing rather than the appointment itself when you offer help. Ask about the getting there and the afterward, which is where the useful gaps usually are. If it is your own day, stop scheduling as though the hour were the cost.
