Lying is often synonymous with an act that is not commendable, ie where there is a difference between what appears and what is not visible, either from speech or deed. For example I will not do that act, in front of us he did not do that act but when we turn around then he did the deed.
Above is the basic understanding of what it is to lie, but here is not always lying is bad or is a dishonorable act, because the act of lying can also be done for a thing that will impact a good.
If you ask whether a lying trait is good ..? Then the answer is there.
I example like this: you have 2 friends, where 2 of your friends are in dispute, here you as a good friend would want to be mediator between your friend disputes. In this case there can do a lie to solve your friend's disputes.
May be a dialogue of lies for example: you go to your first friend and say, you are in dispute with her "second friend" and maybe your first friend replied: yes I am at odds with him, with a scolding or insult of all kinds, so here your role Where you can lie to soothe your first friend maybe with a lie down like that you can say I'm new from home he "second friend" he said he missed you and he remembered when playing with everything just anything that can muffle emotions first friends to friends second.
But here your second friend never say something like this, so here the role of your lie so that your two friends do not disagree again, and vice versa when you go to your second friend lies in the sequence with words so your second friend no longer Hate your second friend.
This is a lie in a good, we lie to solve a problem, many other examples be it in the household, friendship, group or whatever it is, as long as it leads to a positive thing then lie there is nothing wrong to do with the aim for good together.
But instead of doing the opposite of lying to make the noise worse because it could be detrimental.
