People don't generally like blaming themselves. I had this problem with a co-worker of mine. She broke a few things and I called her on it. She got pissed. I couldn't figure it out. Then I realized that she'll wasn't the type of person who would admit that she's wrong. "EJE, it's not like she'll go home, look into the mirror, and say that she's a fucking stupid bitch." Once I realized that, I understood her disability and felt sorry for her.
