I was always very good as a child at it, I could easily spin believable stories. But I can't even remember the last time I properly told a lie to anyone, the only time I get to use my skills now is when I'm with my mates and we will be playing a joke on someone. I always know just how far to push it and the subtleties required to make something believable. I'm quite fascinated by deception it's self, and always loved tricks and magic and playing jokes on people.
Dishonestly is not something I'm proud of being good at but it can come in very handy.
