Every once in a while I find myself in a debate with someone, and it becomes apparent that there is just no way you're going to see eye to eye. In some cases, you have to continue with the debate because the outcome is extremely important.
In other cases, it's fruitless to even debate about it at all because no matter who is right, the outcome remains the same. In those cases, it's simply not worth committing the mental energy to figure it out. I used to use the phrase "we'll just have to agree to disagree", but with some individuals, that's not going to work because they're not really interested in the real meaning of right or wrong. They're interested in proving that you are wrong and they are right.
It's those instances that I've learned to depend on my good ol' Grandpa Hausman's advice and say "You might be right." By using that phrase instead of fueling the fire with "We'll have to agree to disagree" or beating a dead horse and trying to prove my point, I can let the other person feel like they won the debate, and walk away. I feel fine walking away from the debate because I know that all I did was diffuse a meaningless debate (and I know that "you might be right" can also mean "you're probably wrong.")
that is good a good phrase. I have to use that in the future.
