The 10yo Tank and the 6yo Pistol are playing some kind of superhero game with stuffed animals. Tank is getting agitated: “You can’t be invincible, that’s not fair!” Pistol is getting a little weepy, insisting that he wants to be invincible, that it is not unfair! As I am starting to intervene, it occurs to me that Pistol has no idea what “invincible” means.
So I turn to Tank: “Does he mean invincible or invisible?”
Tank: “He means invincible and it’s not fair, then we can’t even play a game!”
Mom to Pistol: “Tell me what invincible means.”
Pistol: “Well, they can’t see him, and …”
Mom gives A Look to Tank.
Tank, looking slightly abashed: “Well, he needs to fix his grammar!”
Mom, abandoning the field, doesn’t even try to fix Tank’s “grammar.”
