I've noticed this year just how quiet it's been. I used to get woken up by all the bird calls, especially in the spring time. Now it's just low level background noise.
The dull and distant bird calls feels so empty, especially since it's been replaced by the continuous hum of air conditioning units and lawn mowers, the violent sounds of vehicle engines with the low rumble of rubber tires and other sources of human activity which never seems to end.
It absolutely breaks my heart.
