Just a tip on how to make such discussions possible to follow (given that this Forum is a public place and not a private interchange between two people 
): When you select something to copy, click on the "Quote button
and your post will not only automatically show readers who you are quoting, as below, but also allows them to click on the upward pointing arrow top right of the quotation, which gives them immediate access to the full context.
It is most helpful when discussants post in ways that help all readers to follow an interchange of ideas.
