The beauty of fundamentals is that they simply never change. 1+1 still equals 2 and making eye contact when you meet someone is still considered good manners.  Even (especially) in the current age of technology and forward movement, I think most of us can benefit from a reminder that not everyone knows everything that we know, and not everyone processes and gathers information in the same way or at the same speed. Whether it be a conversation about social media or a dental patient having a root canal, it is helpful to ensure that all parties involved have common language, context, and understanding if we expect to have quality shared expectations and results.
