I still can't help myself walking round the office switching lights off every so often. It's not just about the Umeme campaign or the current Climate Change rage - mine's a habit formed way back when...
...in the 1980s, during the Obote II regime, I was a kid living in hard times. There was so little of everything that in our household we perfected the science of frugality.

Lights? Off as soon as the sun began to rise. Soap? Used till it turned liquid. Sugar? Not a necessity. Chocolate? Eh? Water? Equalled rain. There was absolutely no nonsense. And this stayed with me right through boarding school, when I'd start and end the term with the same amount of pocket money my friends used up on the first day.

So today, I irritate chaps in the office by stomping about opening blinds and flicking switches off. They don't understand my suspicion that a phone charger plugged into a socket could possibly be sucking up energy and should therefore be discouraged.

Life's short enough without our help, guys. Conserve, conserve, conserve.
