You have to let other people live their lives how they see fit.
It’s far too easy to slip into viewing the world as if you’re the only Player Character, and everyone else is just another Non Player Character. Window dressing to the main storyline of your life. If pressed, most people will deny this, or at least fully acknowledge that everyone has their own lives they are living. And yet, they’ll act like they’re the only ones who truly matter.
So, always be ready to let other people have their moments.
Unless they’re set for a Total Party Kill.
