Why would you deliberately give someone the wrong impression? What would make you alter or exaggerate the facts? Why would you present a false picture?
Whether you call them white lies, fibs, half-truths or exaggerations, lying is lying.
For example, you spill some water on your office's copy machine and it makes a funny sound. Just as you leave the room to find a towel, your boss walks in and tries to make a copy.
He says, "Hey! Why isn't the copier working? And who spilled this water?"
You shrug and mumble, "Umm, don't know" as your face turns red.
You wonder, "Why did I just lie to my boss?"
"Lies are told because one is afraid of the consequences* should one tell the truth." -- L. Ron Hubbard (*consequences = effects, results)
