Small lies add upWatch
To me, it's the 'instant gratification' problem. Do you:
a) Prefer to be lie or be lied to and feel a little better 'in the moment', or
b) Prefer to tell or hear the truth and expose yourself or risk offending someone else, so you can have a more authentic long-term relationship that solves problems instead of ignoring them
Though it shouldn't be just about sharing problems. Successes as well.
But there are some unpleasant truths that must never be mentioned to a very vulnerable person under circumstances where there is a high risk of precipitating extreme terror, a mental breakdown or suicide.
In theory, everyone will say B. But in practice, you see a lot of people who prefer to lie to avoid getting into unpleasant situations.
If I feel like I am faced with people whom I have to lie to to keep them happy, then I'd rather not deal with them at all if I can help it. And that happens quite a lot.
