It was just before midnight when the dog hopped from the bed and started down the hallway. There was a brief light than a sound as the man gently returned to sleep.
As he slipped into unconsciousness, he was sure that the light was the hallway nightlight and the sound, the plastic flap on the dog door. Then it happened again, but he was too far asleep to realize the light had come before the sound when it should have been in reverse.
He felt the dog hop onto the bed and curl up. He’d learn the truth come daylight.
