Here’s the summarized version:

Be Polite.

Act as if you only understand ‘the effects’, have a nebulous notion of ‘the cause’.

Act like you know little other than this, and insist they explain it to you like you are a five year old.

Waste as much of their time as possible, without becoming hotheaded, instead become sad-confused.

“I’m not so much angry, as I am disappointed” type of vibe / energy.

And if possible, be genuinely kind to the low level, actual people you talk to, they literally do not make the rules.
