Aus dem großartigen Rules of Thumb-Blog:
“The other day I learned the rules for playing snowballs with 5-year olds: a.) Be careful to just compact the snowballs enough to make them hold together b.) Aim comfortably wide of the mark. I suddenly realized that these are also good rules for offering criticism to anyone, big or small.” – Robert Westbury

Das würde ich um die Regel ergänzen: Immer locker und offen von vorne, damit der Andere sein Gesicht schützen kann.
