You're so charming that people can almost overlook your blunt honesty. Almost. Trouble is, what you see as frank can border on heartless if you aren't careful.
People will squirm if you talk about that friend who's dumb as a box of rocks, or ask a woman if she cut her own hair. The State Department probably won't be offering you a job, but a little diplomacy would go a long way in your everyday life.
No one's asking you to lie! Just think before you speak. And don't play poker. You'll be the one asking, "Are these cards any good?"
