To make a statement. Banksy's an anonymous artist who makes statements and highlights the things wrong in society. He did this to try to stop people from auctioning thing like this and to let everyone enjoy it, not just the person with the most money.
Mrs.Bush..... I am speechless by this video. In a really good way. She had the best confidence and she is someone who admire now. She was a very strong women so is her husband. I really hope that I can be like her, strong, brave, and confident.
