I pretty much go with the societal norm in everything. As you can see on this thread, the general consensus is that major lies are not ok but small, non hurtful lies are ok. The matter of what is or isn’t ok lies with each person and we all have our own set of personal rules and morals.

In business, I’ve had people majorly lie. As the professional, I know they are lying, but I just gloss over it, not letting them get away with it, but not confronting them for it.
