If the words don’t add up, it’s usually because the truth wasn’t included in the equation.
You lie online. It might be a lie to sell something or a lie to make yourself feel better. You might lie to help somebody else or perhaps to make another feel worse. Perhaps you just exaggerate. You brag. That’s not lying, right? That’s just expanding something to be more than it should be. Surely there’s no harm in that?!
