I think that most people would agree that lying is not good but  there are different degrees of lying.  For example if a friend spent a lot of money to have her hair done and she loved the results but I didn't like the new look, I would not be mean and tell her so.  If she asked me I would say I liked it.  But if someone did something wrong and then lied about it to cover it up - then that is wrong.

Does that make sense Azi.... kind of hard to explain.

Also I read somewhere a while back that most people believe they can tell when someone is lying but the reality is that most people can't recognize a lie unless the lie is so outrageous that it is obviously bs.
