A cross-stitch has hung on the wall of my family home for as long as I can remember. It reads:
I'm developing a tendency to quote this at people when the situation warrants it. They're usually somewhat confused - and explaining that John is my father only alleviates some of it. I quote it at people because it's probably the most important lesson I've ever learnt for getting through life.
Because being correct isn't the only thing that counts.
Having the power to follow through on your correct-ness is also important.
And the other person also has to agree that you're correct before you will ever get anywhere.
And you've really got to think about the consequences of your correct-ness. Will being correct change anything in a positive way? Or will being correct just result in arguments? And are those arguments worth it?
Being correct is not sufficent.
