I'm going to make a prediction - the results of this month's challenge poll will be:
I was already green! I never leave lights on in empty rooms! 100%
I'm always walking round the house and spotting lights left on in empty rooms. I blame the kids, but to be honest I do it, too. So this challenge is really just for me. I'm going to drum it into the kids' heads that they have to turn lights off. Maybe we'll all make posters to remind ourselves to do it. And I'll give them permission to chastise me if I leave any lights on.
So go on, prove whether I'm right or wrong? Am I the only one with this shameful secret? Vote in the poll today.
