Beautiful Liar

I don't enjoy lying.
Occasionally it is necessary and I'm very good at it for the most part, but I still don't like doing it.

Telling a lie may seem like a one-time experience, but a lot of times you have to tell additional lies to maintain the original one...unless you tell a very solid base lie. Where people go wrong is that they tell a completely inaccurate and unrehearsed lie that is usually not consistent with their personality. Bad idea. These are easily unraveled and/or disproved because they were just hastily spun and not well presented. The best lie is one that is so close to the truth that your body feels completely comfortable telling it. There is no need to tell and extravagant story complete with things that fly and outrageous 6 car pile ups when a simple variation on the actual story (one which relieves you from direct responsibility) will suffice. Even in a hopelessly messed up situation where you were supposed to "know better" you can even add an additional scene in which you chastise yourself for a trivial version of the offense, thereby alleviating some of the focus from the actual travesty. Of course the next step is to review your story. The farce should also be well within your normal set of situations...nothing too far fetched, nothing ultra heroic or more conniving than people are accustomed to from you. Practice what you will say and even toss in a mock rebuttal.
Preparation is hugely important because no one wants unanswered questions or motives, so you should plan for at least 2-3 questions that you will not deflect, but intercept and fold into your tale: "Ya that's what I thought too, but he really didn't seem to mind at all...it was weird, but he and I don't even really..."
Delivery should be smooth and somewhat casual if not apologetic. You cannot force them to buy your story, but you CAN tell it as if there is not really an option but to accept it as the truth. You can make people believe things that are explainable false if you present it well enough, but of course you must buy your own story. the lie must become not only the truth for them, but also the truth for you...one that you must now own and not stray from. No one will believe something that you yourself don't believe...and since most of communication is body language, you have to include your entire countenance into your story to ensure its success. Try to make a connection. If you can get the person to empathize with what you're allegedly dealing with, they are far more likely to overlook any details that don't necessarily line up.

Looking straight into some one's eyes and knowing that you're lying and that they are buying it does feel kinda cool though...but I feel like it could easily become addictive and so its best not to even tempt myself with the notion.
....ok maybe I like lying just a little bit
No no I didn't say that.....look into my eyes and you'll see its the truth
