I’m sorry, I am a poor liar
If you happen to be a habitual liar but not quite so good at it. I might even go so far as to say – bad at it, it could be to your advantage of admitting that you are bad at lying. This way, no one will know when you are lying.
This is, according to one poster who gave this ‘sage’ advice. As a general rule of thumb consider not lying about the major things in life that hold the most significance. Perhaps you should also try to do this for things that are important to you and others, too. The truth always wins.
