Trust is falling asleep in someone’s passenger seat.

Sleep is the one thing you cannot fake. Dozing off while somebody drives means your body has stopped checking: not just about the driving, but whether they will laugh at you, photograph you, or wake you badly. You do not decide to relax like that; it either happens or it does not, which makes it a more honest signal than anything you could say.

Notice the handful of people in whose company you actually unclench. That list is probably shorter and different from your list of closest friends. And be the kind of passenger seat somebody else can sleep in, which mostly means not making a story out of it.
