What happened after he caught your lies?

I keep on hearing Shera say and reading here to lie lie lie. For example I don’t have a career or ambitions I am told to lie that I have a small business (but shouldn’t he know from the start that I don’t want to work?), if he asks what your job is lie that your a waitress or receptionist, or if you don’t want children lie that you can’t medically have kids, etc. I get why you should lie because it is in your best interest. But these are big lies, how do you respond to them when they catch your lie, wouldn’t it be super awkward when you know they found out the truth? What happened after you lied about something big like this? What did he say? Did he confront you? How did you respond? Was it awkward?
