I shall begin with an anecdote. In my youth when I was at junior school (that’s 7 to 11 years of age in the UK) I was formally introduced to team sports. At that time, I had no prejudice against them and was happy to participate. However, the sports teacher (a curious breed of human per se) often assumed that we knew the rules of all the most popular sports by default. I can remember the guy getting frustrated regarding the “Leg before Wicket” rule in cricket and that some of us didn’t understand it. “What does it mean?” I asked. “It means leg before wicket” he answered in an exasperated tone. He simply didn’t grasp that I wanted a specific answer that explained why this rule was this way . Since then, I’ve encountered many other examples where people assume that you know what they know.
