After you’ve lit a matchstick, all you are left with is the stick bit. Sure, it’s possible to rub two sticks together to start a fire, but not two sticks the size of toothpicks! So with no fire-lighting ability left in the match, why then would anybody put it back in the matchbox amongst the red-tipped ones that can actually light your BBQ? It’s like putting dirty plates back in the cupboard next to clean ones, or an empty bottle of beer back in the esky. It just doesn’t make any sense at all, or any fire.
