A dialogue about can
That’s the bit of the can that drops down into the drink when we pull the tab.
Yeah, hopefully. Sometimes the tab just breaks off.
I know.
Anyway the opening is scored so that it pushes in easily but doesn’t detach itself.
OK, we can show that by drawing a shadow of it inside the can, like this I’ll label it scored opening.
what's the meaning of "score" or "scored opening"? I did not find interpretation online.
