Little cloud.

In three or four hours time, that little cloud will have transformed into massive, towering rain clouds.
The rain will close deep cracks in the dry, rock hard soil, penetrating deep within the clay soil, which will beome soft and sticky
Olives will swell on the trees and the fruit trees will all sigh with relief, as so will I.
Or it won't rain at all and the olives will dry up and fall off.
