Did you know that in switzerland it is said that if your son wants to get married, you should invite his fiancée for dinner and let her cut the cheese for it.
If she cuts off too much of the cheese with the rind, it means she‘s wasteful.
If she cuts off too little, it means she‘s stingy.
The genius about this is that every family would have a different sweet spot to what‘s considered not too stingy and not too wasteful, which would mean that if they approve of her cheese rind cutting, she would fit right in with the family‘s values concerning finances, which might even translate to a lot of other areas. It‘s brilliant.
