What if I've lied about most of my life?
How do you lie about most of your life?
I usually start by doing something then say I did someone else after.
If you always lie to people when you need to tell someone the truth they will not believe you. It can be harmful to deceive other people.
Whatever. I'm a great liar and I'm proud of it.
You should not deceive other people. This is not the right thing to do and will cause people to distrust you.
