What is the difference between lying and bending the truth?

Yesterday I watched an interesting documentary on how old are we when we start lying. I never really thought about this. What they did was put 4 children around the age of 6 seperately in a room with a delicious chocolate cake. An adult male explained to each of the children that he had to leave the room for 5 minutes but they where not to touch the cake not even a crumb and he would explain when he came back. The experiment was to see when these children thought no one was watching what would they do. Three out of four to the children touched and even tasted a wee bit of the cake. When the gent came back in and asked all four if they touched the cake all denied touching the cake and even given a second chance still stuck to their guns. Such a small experiment but really got me thinking about how often do I lie in a day justifying that it was just a fib or bending the truth. How about you....what are your thoughts?

Lying, it turns out, is something that most of us are very adept at. We lie with ease, in ways big and small, to strangers, co-workers, friends, and loved ones. Our capacity for dishonesty is as fundamental to us as our need to trust others, which ironically makes us terrible at detecting lies. Being deceitful is woven into our very fabric, so much so that it would be truthful to say that to lie is human.
