a small moment

A boy, 9 years old, and his mother walk along on a path along a road. He wears his raincoat casually open; she is huddled into hers. Towers grasp high tension wires and loom like giants overhead. The electricity in the wires crackles in the air.

"What's that sound?" she asks the boy, curious to know what he hears.

The boy pauses. "It's the wires. They sound like cicadas."

His mother tries to remember this moment because he is 9 years old. She likes his idea that electricity snaps the air like cicadas. The boy wants to eat lunch --maybe a sandwich. 

They both wonder how long the walk will continue.
