They say that honesty is always the best policy, I'm not so sure, maybe the truth but rarely the whole truth.
Unusually for me I would like simply quote at length from the novel I'm currently reading.
"Truth is female, since truth is beauty rather than handsomeness; this Ridcully reflected as the Council grumpled in., would certainly explain the the saying that a lie could run around the world before Truth had got it's, correction, her boots on, since she would have to choose which pair - the idea that any woman in a position to choose would have just one pair of boots being beyond rational belief. Indeed as a Goddess she would have lots of shoes, and thus many choices: comfy shoes for home truths, hobnail boots for unpleasant truths' simple clogs for universal truths and possibly some sort of slipper for self evident truth. More important right now was what kind f truth he was going to have to impart to his colleagues, and he decided not on the whole truth, but instead nothing but the truth, which dispensed with the need for honesty"
