Ya see, ya take your lie, and taint it with a sprinkle of truth, so it's even more believable!!! And you occupy yourself while doing so, like doodling, or playing videogames, OOh, and 'looking thru the cupboards for food".
I do too.. It tends to do more harm than good, but if people believe that you just laugh like that no matter what, it could be very useful... Mask a lie by laughing to make it seem like it's a lie, when normally you laugh when you're telling the truth because it seems like a lie... Very complicated and easy to lose people in!
