Wow, mum. This place is so big that you could get lost in here!
That's right, so keep close to me
OK. what are you looking at?
I'm trying to decide which bag of rice to buy
Why are they all different prices?
Some rice is better quality and some are bigger bags.
Oh, so why are you buying that one?
Because the grains remain separate when it's cooked and being a bigger bag the price per kilo is lower
Then can we get a big bag of these toffee lollies, too?
That may be you false economy, Tommy
What do you mean? If you get a bigger bag each lolly is 2 cents cheaper
Yes, but because you have more, you eat more and the bag runs out almost as quickly!
OK
