【简答题】
We do not make mistakes on the basis of race of color. We do not make them because we are male or female, young or old. We do not make mistakes of choice or judgment because we want to make mistakes. We make them because we are human. Mistakes, bad judgments, the stupid things we do are all a part of being human. We cannot hide from who we are. We should not hide from what we do. When we acknowledge our mistakes or errors and face up to our human shortmings, no one can use them against us.
