You can never win from a Machiavellian, insidious and canny person. And trust me, don’t even try.
No, I am not telling you that you can’t win. You definitely can. I know you can and you will win. But in that process you will lose your peace of mind.
You will end up becoming someone you never want to be.
It’s like they will drag you to their level and then defeat you with their experience.
So it’s better you don’t get into the mess and ensure peace.
