There are two ways to explain mistakes: the person did what they did because of the situation, or, because of who they are. We use the former explanation with ourselves — “I forgot her birthday because I have so much on my mind right now.” We tend to use the second explanation on others — “She forgot my birthday because she’s so self-centered.”
