I wrote to Bill Gates and received a reply. In 2004, an Indian from the same school wrote to Bill Gates, saying how bad he was, how hard life in Germany was, and how depressed he was, hoping to get help from Bill Gates. As a result, Bill Gates wrote back to him. The letter was printed, but the signature was written by Bill Gates in pen. Most importantly, this letter directly contains 1000 euros in cash. I regret it. I wrote a letter that night and sent it to the post office the next day. After waiting for almost two months, I finally wrote back. What I wrote in my letter is exactly the same as what I wrote across the hall. It seems that they are all form letters. I only hope that we can overcome difficulties, study hard and make progress every day.
