I suppose to understand everyone clearly we could insist that they use terms exactly as we do. Although it reminds me of a good friend who was an English professor. Grammar was not my strong suit in school, so I was always a bit tenative when speaking around him. At one point we were sitting out on his deck and he asked me why I spoke so carefully. So I told him about being a bit self conscious about my poor grammar. He laughed for about five minutes and when he stopped he told me, You get your point across just fine and after all communication is not about the words, it's about communicating an idea.
He also shared another idea that I have tried to use, It is much more difficult to craft a lesson and present a complex idea at a six year old level than it is to craft a presentation at a college student's level. Ironically, it is the college student who will not listen as well as the six year old, so in many cases you end up using the six year old level presentation with them as well.
I think we see TDK's video similarly. Although we described it differently.
