Looking for silence in the park

Can there be silence in city park? Dark quiet hot Summer night, sitting by an artificial lake. The lake features is a small constructed waterfall. Fireflies are dancing in the grass, flicking their light "on" "off". To my delight, they surround me. The cooling effect of large old trees is felt, a few people socially distancing are relaxing. Because of the pandemic activity is reduced. In the distance a motorbike, and the on-going rumbling of traffic. It is quiet, and in this quietness, the sounds and constant humming of the city (buildings, buses, etc.) is even more apparent.
