You did a really good job explaining this in a clear and easy metaphor that can easily be pictured. Seeing something in your mind makes it easy to remember! Also, I have a copy of that book, it is the ABSOLUTE best for learning, everyone is an image I can easily picture and this remember.

Its frustrating how university professors are just scrolling down and reading a pdf file on zoom without showing examples and explaining this way . they believe they are doing a good job but they are just useless they are getting paid for nothing ... Thank you very much for the explanation =)
