I'm going to lie to my boss.
That is not good, why do you want to lie to him?
I don't like the way he treats me, and I think he is an idiot.
It can difficult dealing with a boss that you don't like, but lying to them won't make things better. If your boss finds out you lied, your job could be in serious trouble. You may even get fired depending on what you lie about.
There is no way my boss can know that I lied. It's not like he is a mind reader.
Your boss will find out eventually. You shouldn't lie to your boss for any reason. This could impact your future jobs and even your job at the company.
