All in all, as you see telling a lie will be appropriate and inevitable as a solution of some problems. With telling a lie we can manage our relationship and keep the friendship. There are many ways to tell a lie in some events, and telling a lie is more profitable than telling the truth. In my opinion, sometimes our lives are full of lies and the real becomes a lie with not telling the truth. The truths can be changed and there is no person who says "I have never told a lie". If he/she says "I have never told a lie" , we can understand that he/she is a real liar.
