My brother inlaw and his daughter watch DVD's and the repeat scene after scene with each other. Its hilarious to watch and they get they accent spot on. Some people are blessed with minds that can retain volumes of information.
I think they are so gifted. Maybe you could use this talent to do something?
Would you like to be an actor or go to university and learn? Its obvious that you have an ability to retain details that others cannot.
Maybe start to see things from the other angle?
