,,,,I think that list of examples, by smallbutmighty, are good ones...…
I will offer another tip....for when someone (like your son)….is blaming, accusing, demeaning, etc....is not o get sucked further into the circular arguments....as cited by smallbutmighty...….
Do not JADE.....
J...justify yourself. A....don't argue. Youdon't have to attend every argument that you are invited to. D....defend. You don't have to defend yourself...E....you don't have to explain yourself.....
When you don't JADE...that is drawing a boundary.....
