You're on the
Make it count!
I must admit that I'm in danger of being something of a pin in the neck to other people. It drives me nuts to go into other people house and see that they just leave loads of lights on, or have the temperature up way too high. Havin a big fancy energy wasting fridge is a crime in my book too. All of this is mainly because I'm on a tight budget - it's not's about saving money, not the planet.
Most of the time I just bite my tongue, as after all there's only so much you can say before you don't get invited round ever again ;-)
