The man with the Hearing Aid
A man takes out his hearing aid and falls asleep, his good ear deep in the pillow. Thousands of bats fly out of the other ear.
All night they flutter and dive
through laughter, catching the punch lines, their ears all blood and velvet.
At dawn they return. The weary squeaks make the old stone cavern ring
with gibberish. As the man awakens, the last of the bats folds into sleep. His ear is thick with fur and silence.
