It seems that whenever lying is being discussed people are quick to come up with justifications for why it’s okay in certain situations, the classic one being that you were served food that you didn’t like but when asked said that you did.
This seems to assume that the other people in fact would have preferred the lie over the truth. So I ask: when do you yourself prefer the lie?
Controlling emotional responses is more about how strong they are and if that has a negative effect, not about keeping them in and not showing them.
