Web alarm clock for 8:00 p.m.
As you hand over the job of bringing chairs for the evening Mass, set the alarm for 8:00 pm and tell the next person what still needs carrying. A clear handover helps them know whether the chairs are waiting by the parish hall, already inside the church, or still need to be collected.
The chair handover may happen while people are chatting, traffic is passing outside, or a sound system is being tested. Set the alarm loud enough to stand out from that background noise, then check it from the place where the person taking over will wait. Keep this browser running and the phone awake; otherwise, the chair reminder may make no sound, leaving the next person unaware that it is time to move them.
Once the chairs are in place that evening, allow a small buffer before the next commitment on your schedule. At 8:00 pm, parish activity can overlap with supper, a ride home, or another household task. Decide during the handover who will confirm that the aisles remain clear, then note when you need to leave. That margin keeps one delayed chair run from pushing everything else later.
