A childhood belief about mirrors

I'm not sure if I believed this or not, or just parts of it, but when I was about six years old my older brother (who was totally mean at around eight years old) told me that I was so ugly Mum and Dad had to pay for people to act as me on the other side of mirrors (not just in our house but everywhere I ever went) so I would not see what I looked like and could have a 'normal' life without the stigma of knowing I was so ugly. He also said this was why our family was 'poor'. He said it was really tricky getting people who looked like the rest of the family to act like them behind the 'mirrors'. It was a pretty convuluted story for him to make up which might be why I thought it was true. What a mean big brother! The absolute meanest bit was that he said the person they got to act as me was just 'average looking, not too pretty' so that I wouldn't think I was beautiful or anything like that. They didn't want me to be overconfident. Ouch!
