Someone else ever gotten the credit for something you did?

No...but I got blamed and punished (unjustified) for something I didn't do at school. And the teacher didn't believe me when I told her I didn't do it. I went to my mother (who knew I didn't lie) and she went with me to see the principal, who talked to the teacher and the class. I never knew who said what to who, but the principal came back to the office and said, "Send your daughter back tomorrow. It's taken care of."
