On making mistakes

　　"The only man who never makes mistakes is the man who never does anything." Obsolete as it may sound, the saying is quite sensible. It indicates that to err is human, as was remarked centuries ago by Alexander Pope, the renowned British poet. Strangely enough, people exert great efforts to avoid making mistakes, which actually are part of our life. Let's name but a few. First, we may take the wrong steps when we first learn to toddle, and fall over. However, we learn how to walk and run from it. Second, we may make friends with someone who is a hypocrite, and get hurt.
