You never have, and.never will. The only time you might ever concede is if it was part of winning a bigger argument, netting you a bigger win.
You always change the subject, drop the subject, attack something no one is talking about (then blame the other person for it), play semantics, call to authority / experience , nonsense reply, verbal ass slapping, tldr.
You have never said "yoshi, I've never thought about it that way, you might be right."
