A note tucked into a lunch can travel farther into the day than its writer does.

A written line keeps working long after the person who wrote it has gone to work. Whoever packed it is elsewhere by lunchtime, and the note arrives in a canteen or a classroom, carrying their attention into a room they will never enter. A few words cover a lot of distance.

Write one this week, for a child, a partner or a flatmate, and keep it ordinary rather than momentous. A line about the day is plenty. What is really being delivered is the fact that somebody was thinking about them at eight in the morning.
