We are all someone else's NPC. Even the worldwide famous movie stars. Even the billionaires.
My 11 y/o daughter loves the concept: there's this guy, he always walk his dog at the same hours. We always see him in the neighborhood: same route, same hours, same dog (obviously). And we just call him "the NPC". And seeing the NPC is something for us: if one of us sees it, we mention it to the others. But we always keep in mind that every single one of us are someone else's NPC.
Just to be clear: we're not making fun of the NPC. And we're totally okay with others calling us NPCs.
> be an npc. drive a boring car—who gives a fuck?
Or, you know, don't give a fuck and drive the car you want to drive: a boring car, or an old wreck (which can be either boring or not), a 2CV [1] (a friend drives one --and the same one-- daily since... 35 years), a Toyota Corolla, a Porsche 911... Whatever the heck you feel like owning. For you, not for what the others think.
