   Bill Gates' friends knew that he was different even when they were children. One of them, "We all knew that Bill was cleverer than us. Sometimes we could not understand him."
   Bill was also top of his classmates in math and science, so his parents sent him to Lakeside-a boys' school for excellent students. It was Seattle's most famous school.
   In 1968, the school made a decision that changed thirteen-year-old Bill Gates' life. In that school, money was given mainly by parents, which could make the school have a computer and use it through a teletype machine. The students typed in a few words on the teletype machine and a few seconds later the computer typed back to students. Bill Gates was interested in it at once. From them on, nothing could stop Bill from studying it. Whenever he was free, he would run to the computer room to use the machine. He became so excited about it that he soon was much better than his teachers in knowledge of computers.
   At fourteen, Bill was already writing short programs for the computer. And they were written in what was so become Bill's second language, BASIC.
   Why was Bill Gates sent to Lakeside?
