I'm a pathological liar
Why do you like to lie?
Because I find it fun to see if I can trick people with my lies.
Lying to trick people is wrong to do. You should not do that to people.
No it's fine. All lies are good, especially if you are lying for a good cause, like to save a friendship.
All lies are not good. People are not going to trust you if you keep lying to them like that.
