Toast

She sat and ate her toast with Marmite. She knew that some people, most in fact, hated it, but that was their loss.
There was a knock at the front door.
She went to investigate. It was the postman with a letter that he said was too big for the letterbox although it clearly wasn't.
She returned to the table. The toast was gone.
Her dog sat under the table attempting to look innocent. The crust by his side and the crumbs in his whiskers told a different story.
