What is Truth? I mean what is true for me is not always true for someone else.
Has it not happen to you that something happens, you are there and you are with another person. Later, you hear the other person tell someone else the story, and what you hear him say is not how you saw it, his version is totally different from yours, yet you where both there!
Who to belief, who is telling the truth?
And in another situation the truth is not that nice so we change the version a little bit, mostly to make our selfs look better then what is really true.
And then there´s the situation when the truth is a little boring and we spice it a bit to make the story more fun.
Or just tell the truth, the hole truth and nothing but the truth.
