Hostile messages beg for the reply that makes everything worse.
When an email attacks your character, your competence, or your decisions, the instinct is to defend, correct, and counter. That reply becomes ammunition, and the thread grows. A BIFF Response® does the opposite: it answers with something Brief, Informative, Friendly, and Firm, gives the other person nothing to grab onto, and usually ends the exchange.
