How often do you allow yourself to deviate from your attitude in a discussion?

[deucher]

I am quite a controversial person and if I enter into a discussion with a person who tells an absolute lie that is even directed against me, then I will stand my ground until the end, but when the conversation drags on and the person's eyes show that he understands what the truth is but continues to say nonsense, then I just I will say that she is right and I will end this conversation because I understand that there are some people who cannot admit their mistakes and I can.
