"When a mystery is too overpowering, one dare not disobey. Absurd as it might seem to me, a thousand miles from any human habitation and in danger of death, I took out of my pocket a sheet of paper and my fountain-pen. But then I remembered how my studies had been concentrated on geography, history, arithmetic, and grammar, and I told the little chap (a little crossly, too) that I did not know how to draw. He answered me:"That doesn‘t matter. Draw me a sheep..."
It seems ridiculous, doesn‘t it ? But it absolutely exists in our life.
But that did not really surprise me much. I knew very well that in addition to the great planets-- such as the Earth, Jupiter, Mars, Venus-- to which we have given names, there are also hundreds of others, some of which are so small that one has a hard time seeing them through the telescope. When an astronomer discovers one of these he does not give it a name, but only a number. He might call it, for example, "Asteroid 325."
Amazing imagination!
A journey begins……

If you were to say to the grown-ups: "I saw a beautiful house made of rosy brick, with geraniums in the windows and doves on the roof," they would not be able to get any idea of that house at all. You would have to say to them: "I saw a house that cost $20,000." Then they would exclaim: "Oh, what a pretty house that is!"
