In this talk about cooperative lies they talk about how lying is bad but how in many aspects it can be good. Lying is typically not a good thing to do but if it is keeping you from making someone feel bad or being ashamed of themselves there is no problem with that.  I totally agree in lies being a cooperative act because there are definitely times to lie and times to not.  People always have lied and always will, there is nobody in the world who hasn't lied about something because it is in our nature.  If it spares someone's feelings a lie is definitely worth it because you may tell the lie and think maybe I should have been honest but if it makes them feel good then it's worth it because making someone feel good will last them way longer and make them feel way better than you will feel bad about the lie.
