Take doctors, for example. A few years ago, whatever they said was gospel. Patients took their opinions and instructions at face value. Now, with the availabilty of information on the Internet, patients can check behind their doctors. We can check to make sure they haven't been sued for malpractice. When they prescribe medicines, we can check side-effects and interactions. Yep, the Internet is a valuable tool.
Another example are teachers and principals. My granddaughter was born prematurely. Her development in some areas was slow. Several times, teachers wanted to label her as "challenged." Her middle school principal told her parents she'd never be a scholar, never qualify for college, never...yeah, you get the picture.
I've called her Sugar Dumplin' since she was a tiny infant. I may need to change her nickname to reflect her grown up status. Then again, maybe not. As determined as she can be, she probably wouldn't answer to anything else.
Sometimes it warms the heart when experts are wrong.
