About Liar?

I don't mind people when they say a joke even if they lied here , it is in the range of the acceptance, but if he went beyond these and lied directly to me I won't belive him anymore, because if someone lied on you one time he may do it again and again.

A liar is that person who tells the untruth deliberately to gain an undeserved advantage or to escape from a deserved punishment or condemnation. A joke, if admitted so, is not a lie, even if it contains some elements of a lie. Ditto for imaginative stories. Lies are told to deceive; jokes and imaginative stories are told to create fun or to teach a lesson.

well i will not tell someone that he is a liar because his imagination is working too well. bu ti will call someone a liar if he/she told a lie about me to someone else... or if she put up something against someone that is not true.
