Everything in the garden is humming

Every evening, as I get ready for bed, I open the bedroom window, not for the fresh air, but for the sounds in the garden. I'm not a naturalist, so I can't say for certain how the insects in the garden make their indescribable but delicious night music. Maybe they rub their feet together, if they have feet, or maybe they are playing teeny tiny musical instruments. Anyway, the garden is alive with summer sounds and I dread the day that autumn comes and stills their music.
