We sleep in summer with our windows open.
As the evening falls, the hum of air conditioners seems to take to the air. We live close to an institution that has large fans and mechanical activity. After a while this becomes usual.
Near day break, our silence is broken by new sounds. Trucks begin to arrive with annoying back up signals. The traffic on the nearby highway begins to accelerate. As the hour turns, and people are headed to their workplaces, the decibels rise and fall accordingly.
Mid morning seems to carry more quiet, as air conditioners become less active and sometimes even silent. The traffic slows and the sun is often shining. Late afternoon then accelerates with return from work and evening activities awakening noises of lawn mowers and house renovations.
When the evening returns, the flow finishes its cycle. In this there is regularity. And a sense of continuity. When life has ups and downs, the reminder that God makes sure the sun rises and sets is a settling thing!
