Throughout each day and week of our lives there are often disagreements. Both people often began an argument thinking that they are right. But halfway through the discussion I can start to see their side... most of the time. But do I stop disagreeing? Probably not. I just keep trying to find more reasons why I'm right and they're wrong. Why?
I think it all goes back to pride. When we realize that we've made a mistake or mispoke we refuse to swallow our pride. It's almost like a switch that just gets turned on as soon someone says we are wrong. We just immediately start getting all defensive.
The solution, I think, is just practice. Try to take a step back and really think about whether or not what the person is saying is true. Sometimes it's ok to call a time-out.
