Voices in the night

Last night, I woke to the sound of a man and a woman talking, softly, in the distance.
I opened my eyes. It was very dark.
I turned to look out of the window. No one was outside.
I started making a list:
The strange and quiet couple next door? No.
The young people across the yard? No.
Joey's television? No.
My radio? No.
My alarm clock? No.
Any of the other neighbors? No.
I'm pretty sure we don't have ghosts, I reassured myself.
I listened harder.
The air conditioner? No.
Then it hit me.
I reached out and touched my cat's belly, waking her up.
The snoring stopped.
