In college while working at the library, I overheard a young woman saying to her friend "just once I would like to hear him say that he was wrong and that I was right"
Well I can't claim to be a champion at relationships, I do believe this has served me well over the years.

I think, in the long run, the humility to admit wrong-saying does more for credibility than making excuses.
