The colour of money

Since his 6th birthday M. is
1. allowed to use a knife ("ik ben zes en ik mag een mes")
2. getting 20 cts pocket money a week.

I know.
20 cts doesn't really get you far nowadays but on the other hand; whenever they really want something we just give it to them. It's more to make him understand you simply have to wait and save money if you want to have something and some things are more expensive than others. Now he has been behaving like Dagobert Duck, endlessly counting his money and it just burned in his pocket and today he couldn't hold it any longer. He wanted to buy a dragon egg.
We went to Intertoys, to the counter, he put 30 cts on it and looked up to me, hoping to hear that was it.
After i urged him to keep on going, he said; even my little paper? (he had a 5 euro note).
Yes son, even your paper.
On the way back he was clearly divided and you could almost hear him think
Man, a dragon egg is the coolest, but it just stinks you have to loose your money for it.

Getting wiser doesn't always make you happier.
