We have an little devise from Scottish power that shows you how much electricity you are using. You’re meant to be able to use it to save energy and money. Its getting on my nerves. If I am the last person to leave the house I check it make sure that I have turned everything off. I had to go back and check it fourteen times one day last week, just to make sure. Actually I was happy the thirteenth time but popped back once more because thirteen is unlucky for some.
