I thought the article was very insightful.

A few points from me:
1. I would not have used the terms shame and aggresive for the things he was saying to do.  I would say it was being increasingly assertive.  I do not think it is ever correct to be aggressive in such a situation.  I would also say he was asking for courtesy, not shaming, at least I hope not, and being increasing blunt.

2. I would caution people to not use shame or aggressive methods.  Some people can react violently to shame and/or aggression.  The person may end up hating you, even if nothing happens.

3. If you feel getting caught up and losing your cool, you need to take a time out.

4. Have a safe place  and/or safe people to go to after a stressful encounter.  During this time meditate on what you could have done better and resolve to do that the next time.
