Credibility

I've heard so much about gaining credibility and yet life and close ones don't cease to amaze me. No matter how much I know, it will always be Emily Post's etiquette book that will prevail with the right gift to bring to a friend in mourning. It always be my brother that will ascertain that Quid pro quod can be correctly used as misundersatnding in the Portuguese language. Even if they say the exact same thing I had already said. Maybe my role is just to be the last one to be served the wine.
Cialdini knows best and has said it over and over in here.
