It seems to be strange to you there is a blind spot on the eyes. Here is an interesting experiment that can make something disappear, when one eye is open.

Make a card about the size of a postcard and write two English letters L and R on it, L on the left and R on the right. First, hold the card about 80 cm away and you see both the letters. Then close your right eye and look at the letter R only with your left eye. And now, as you move the card slowly towards you, you’ll find the letter L disappearing. But if you move the card nearer to your face, the letter will be seen again. Now do the same experiment with your left eye closed, you’ll find the letter R disappearing.

Why does the letter disappear? It is because there is a blind spot on the eye. When the image of the letter falls on the blind spot, it won’t be seen. That is why either of the letters disappears.

A friend of mine named Paul received an expensive car from his brother as a Christmas present. On Christmas Eve when Paul came out of his office, a street urchin (顽童) was walking around the shining car. “Is this your car, sir?” he asked.

Paul answered, “Yes, my brother gave it to me for Christmas.” The boy was surprised. “You mean your brother gave it to you and it didn’t cost you anything? Boy, I wish...” He he sitated (迟疑).

Of course Paul knew what he was going to wish for. He was going to wish he had a brother like that. But what the boy said surprised Paul greatly.

“I wish,” the boy went on, “that I could be a brother like that.” Paul looked at the boy in surprise, then he said again, “Would you like to take a ride in my car?”

“Oh yes, I’d love that.”

After a short ride, the boy turned and with his eyes shining, said, “Sir, would you mind dri ving in front of my house?”

Paul smiled a little. He thought he knew what the boy wanted. He wanted to show his neighbors that he could ride home in a big car. But Paul was wrong again. “Will you stop where those two steps are?” the boy asked.

He ran up to the steps. Then in a short while Paul heard him coming back, but he was not coming fast. He was carrying his little crippled (瘸腿的) brother. He sat him down on the step and pointed (指向) to the car.

“There she is, Buddy, just like I told you upstairs. His brother gave it to him for Christmas and it didn’t cost him a cent. And some day I’m going to give you one just like it ... then you can see for yourself all the nice things in the Christmas windows that I’ve been trying to tell you about.”
