 Sometimes something looks different from another thing,but it is usually the same. Sometimes something looks the same as another thing,but it is really different.

Sometimes we cannot believe our eyes. Here is an example. If we are standing in front of an entrance of a tunnel,we can see the other end where we go out. We feel the entrance much bigger than the other end. If we go through the tunnel,we find that the ends are the same size. One is not bigger than the other. They are the same size.

Now let’s turn around and look through the tunnel from the other end. Now we find that the end near us looks bigger. The other end looks smaller. But we know that they are the same size.

Things that are near us seem big. Things that are not near us seem small. We know that one lamp post in the streets is just like another. They are all equally tall. But if an artist draws a picture of a street,he will not make the lamp posts all the same size. He will make the first one big,the second one a little smaller,and the third one a little smaller than the second one. The ones that are the farthest away are the smallest. When things move away,they look smaller. When things come nearer,they look bigger.

 When Paolo was ten years old,he had a very exciting experience. It was a real adventure.

He and his father rose early to go fishing. They got in the boat and his father started rowing out to the sea. The sun was rising as they left the shore. They were going to an area about 12 miles away where the fishing was very good. When they got there,Paolo helped his father with the big net. As they threw the net into the water,it caught Paolo’s foot,and he was pulled into the water. “Help!” he cried, “I’m caught in the net!” His father was afraid that if he jumped in to save his son,he would get in the net himself,and they would both go down into the water. He quickly saw what he must do. He grasped the sides of the net and pulled Paolo out of the water just like a big fish!

Paolo had been very frightened and swallowed a lot of water,but he was soon laughing with his father about his first real adventure.
