Snack attack!

I have a tall resident ghost, who I've nicknamed Lofty. One evening, I was watching TV when an advert came on featuring a man who was Lofty's double. ‘That just looks like you!’ I said out loud. All of a sudden there were three loud knocks on the coffee table and the lights went out! Petrified, I ran to my neighbour’s and she came round with a torch. We couldn’t find anything wrong, but the snack I’d been eating had been finished. Lofty was obviously hungry. Now I don’t risk talking to him unless it’s daylight! Margaret Meager, Berkhamsted
