You will write a book/books at some point. I will not wait to get my hands on it or them. Very good. Thank you for all your knowledge.

Great information and guidance. Two things to help me follow along. 1. You quoted an example of people living in the same house, bit could you then reference back to this example to continue helping us simplify what it means. 2.Can you create a playground which we can also create and build worked examples so we can get our hands dirty?
