when you are face to face with people they don't have a google search option at the ready to counter a point or make a wise retort. either you know something or you don't.
Or more often you think you know something, and you say it with enough authority and conviction that your listeners are hesitant to call you on it.
These are both so true. When I have face to face political conversations (and I have politicians and lobbyists in my family, and we have a family that is very politically diverse and opinionated as hell, so these conversations often come up once we are good and drunk) one of two things happen;
1) I can't articulate what I am trying to say properly and just make it more confusing. Or,
2) If I am not 100% sure about something, I either hedge like crazy or just don't say anything at all.
But what i will do, and my family and friends hate this, is I will email them later once I get all the info straight and try to crush them if they are wrong (or at least I think they are wrong) lol.
