It depends upon who's right.
This.
Admitting that I'm wrong to someone I like and respect is fairly easy.
But having to admit that I'm wrong to someone that I dislike and don't respect can be a serious blow to my pride.
Because, in the latter case, being wrong would imply one of two things:
--either my judgment about this person was mistaken, along with my judgment about the particular question;
--or my judgment about this person was correct, but they caught me off guard, or got lucky.
But to be perfectly honest, I'm pretty sensitive on this issue, even with people I like and respect.
For example: I have sometimes found myself in situations where the wrongdoing and misunderstanding was mutual. In such a situation, if I like and respect the person involved, I will often make the first move, admit I was wrong, and apologize.
If the other person then admits their
own wrongdoing and apologizes, well and good. This can actually improve my opinion of them: it shows they understand the seriousness of these type of situations.
But if they refuse to reciprocate--that can really piss me off, and destroy any goodwill I feel toward them.
I had this happen just recently, in fact.
