Cicadas

What a cacophony of sound. I have never heard anything like it, not even the frogs in the pond beside our house in Nova Scotia. The cicadas go through a life cycle incubating or whatever in the ground for 14 years before metamorphising. They then make up for their subterranean exile and rise to their lofty perch in the trees. For a month only! They are so deafening they drown out all else. Nature sure seems to have come up with an exercise in futility with this one. Probably what the junior, middle and senior students in my classes are saying about my teaching.
