Children of the Self Absorbed; Who You were Meant to Be; My Parents' Keeper:

"Children of the Self Absorbed" by Nina W Brown.
The early edition gave superb tips about being the presence of N people.  Like never eye contacting, where to sit when they are in the room so they cannot give off bad energy to you etc. etc.

I found this one good as it seems I was the parent and NM the child.  Parentification in other words which is hard to escape.
