i had the best biology teacher in school and she made the subject come alive for me she was of grandma age imagine a mrs doubtfire and would make me sit at the front of class to keep my attention i would frustrate the hell out of her with my constant need for explanation i couldnt take any information as fact because i needed to know the why even if it was way above the level of understanding we needed and much to the annoyance of my entire class  i loved that woman  it was only 25 years later i get diagnosed with adhd when my psychiatrist asks me what i was like in school and i clearly remember her school report saying i was very engaging in class and asked brilliant questions but never could complete any homework or be expected to work quietly without interruption
