You know how some guys/”bros” when they greet each other, they do that bro hug/handshake? And sometimes the handshake has like 4 different components. And as far as I can see, every handshake with every pair of guys is different.
How does this work? How do you know what thing to do? Is it improvised on the spot? Do you telegraph it to each other somehow? Does the one who asserts his personal handshake become the alpha? If you do the wrong thing, do you fail the test? How do you know which thing??
I would never know which thing.
