The watering can is heavy because attention sometimes has to be carried.

Care is not only a feeling; quite often it is a weight you pick up and move. The plants do not benefit from your good intentions about them, only from the actual trips across the garden with something heavy in your hand. This is true of most tending: the part that counts is the effort that happens on the days you would rather not.

Choose one thing or person you have been caring about mainly in your head. Do the physical version this week, the trip, the errand, the visit. It is heavier than thinking about it, and it is the part that arrives.
