Synchronizing shared reality
There are also interesting issues about shared reality. If you live in
different and distinct realities, it is very frustrating not to get the
other person to synchronize into your reality - to see what you see and to
feel what you feel. This frustration is even stronger for people who do not
live in multiple realities - and therefore are used to switching
perspectives. (Side note: that is the strongest reason why I wanted
my kids to go through French immersion - not just another language, but a
different and distinct way of perceiving and interpreting the world.)
