Where did that dumb "never apologize" come from? Gibbs on NCIS? The Marines?
Fiorella understands that if one has done something untoward, excuses are--well--no excuse, but that a simple apology is called for and can clear the air. It's a form of courtesy--of extending a peaceful hand to whomever one has, usually inadvertently, offended--and she wishes politicians and nations would take up the practice too.
Fio herself apologizes to everyone and everything--even the table leg when she accidentally knocks into it.
