However, in many of the third world countries, once you have lied, you are always a liar, no matter what.What does third world countries have to do with anything?
I don't care what country you're from, once you know someone lied/lies to you, you never again know when they're not lying
Most first world countries, the person you are talking to can, in some cases, look past why you lied and accept whatever reasoning you use; i.e. I was protecting you, what you don’t know cannot hurt you, whatever.
In the third world countries I have worked in, they would not mentally accept any of those reasons or excuses.
