Today I taught a 60 year old lady how to operate a forklift at work. She has never driven a car nor rode a bicycle. This wasn't an easy task. At the end (about an hour or two later) she thanked me and said I was a good teacher. She liked that I kept my cool the entire time. I told her I knew what it meant being screamed at when learning myself how to drive a car (operating a forklift is just like driving a car). I said yelling and screaming won't help you learn. Not only do people yell at her but she doesn't understand them half the time. Her first language is French. She's also very skittish and unsure of herself and people just don't understand what it's like. What she doesn't know is I've been there. So not only can I relate but I can accommodate my teaching methods to suit her needs.
No one is retarded as some think she is. Everyone just learns differently. What works for some doesn't work for others. I mean even Helen Keller learned how to read and write and speak. If you don't know the Helen Keller story you best go read about it. No one should be insulted or put down for the lack of knowledge. Knowledge is power. Some use it to abuse others. It makes them look like fools.
