I might be #1024 who thinks of this - imagine there would be a type of logic - Balloonean, same as Boolean but specifically for inflation.
Balloonean value can be FULL or EMPTY
Balloonean logic operator OR gives result FULL if only one of two inflatees is full
For example, YOU OR AIRTANK = FULL
That's a little too much for the average person to think about Lopni.
Fill 'er up!
