Web alarm clock for 2:56 p.m.
As you hand over the trip to bring lunch to a relative working in a rice field, set the alarm for 2:56 pm and pass along the plan: leave promptly, check the packed meal, and take the familiar path. The alert gives the next person a clear cue before 3:00 pm, without relying on a hurried reminder shouted across the house or sent after they have already left.
Because the lunch delivery is changing hands, test the sound now, while both of you can confirm that it is loud enough to notice. Keep the browser running and the phone awake until the alarm sounds; if either is shut down beforehand, the lunch reminder may never be heard and the trip could start late. A quick trial also catches muted audio or a volume setting left low after watching videos.
For a midday handover, leave a small buffer after the alarm instead of scheduling the next task immediately. Allow time to collect water, secure the lunch container against spills, and account for heat or slower travel along rural roads. That spare margin keeps the rest of the afternoon usable if the field is farther away than expected or the relative is working in another section.
