People usually hate mice, but one mouse has won the hearts of the people all over the world. That is the famous Mickey Mouse.
Sixty years ago, most movies were silent. A man named Walt Disney made a cartoon mouse that could talk in his movies. He named his mouse Mickey Mouse. People were very excited at the talking mouse. Soon Mickey became a great success among both young and old people. Children loved to see their lovely friends, because he brought joy and laugh to them. Mickey was a clean mouse right from the beginning. Perhaps this is one reason why people love Mickey Mouse though they hate real mice.
In his early life, Mickey also made some mistakes. People were very angry. They wrote to Disney and said that they didn’t want Mickey to do silly things. As there were certain things Mickey could not do, Disney made a new animal—Donald Duck. He also made a dog named Pluto. This dog does silly things and makes mistakes wherever he goes. Now our Mickey is not only clean, but more important. He appears as a star of beauty and wisdom. He has his friends in almost every country.
