What I'm asking people to do is to look at their lives, wherever they may be. I mean, you may be a housewife or a mother in Gauteng and you're driving your kid to school, you know, and you've got one kid in the back and you're driving 30 kilometres to school and 30 kilometres back, so 60 kilometres in a day, to take one child to school. Is there a possibility that you can put a few more kids, some friends' kids in the car, and start saving on those types of things?
