The napkin diagram is wrong on purpose. It compares two toys:

Die: binary, fast, rude honestly. Pair: ternary, slower, rude politely.
Side-by-side
| Die | Pair | |
|---|---|---|
| Faces that matter | six, but you only read top | two blocks, four faces, three pair-states |
| Vibe | casino | parlor game |
| Best question | “Pick A or B” | “Is this sentence ready?” |
| Worst question | “Fix my year” | “Fix my year” |
When to use which
Use a die when you already know the options are equal and you want speed.
Use the pair when you want a third answer that says “not yet / not clear,” which is often the adult answer.
House rule
Neither toy pays rent. Neither toy signs contracts. Pay the diner bill with money.
