Web alarm clock for 1:42 p.m.
You are halfway through another chore when you remember the rice drying outside needs to be moved under cover. Set the alarm for 1:42 pm so you can keep working without repeatedly checking the time, then break away when it sounds. That leaves the rice sheltered well before 2:00 pm rather than forgotten while your attention stays on the job in front of you.
Because the rice depends on you hearing the alert, test the sound now, before returning to what you were doing. Set a trial alarm for the next minute, keep the volume clearly audible, and confirm that the tone plays through your phone. For the real alert, leave the browser running and keep the phone awake; if either is shut down, the rice reminder may never sound, and your work elsewhere could carry on past 1:42 pm.
Once the rice is under the cover, midday heat can make a cold glass of water or calamansi juice a sensible pause before you resume the afternoon's tasks. If merienda is already prepared, save heavier food for after the move so eating does not turn a quick interruption into a longer delay. A light drink beforehand is easier to finish while keeping 1:42 pm clear for the one job that brought you outside.
