One of the most important skills I learnt as a kid, from my family, is learning how to disagree without taking it personally. My parents couldn't possibly be more different from my sister and I. They also encouraged us to have meaty discussions and debates, everyday at the dinner table. Over the years, we've had some very passionate and spirited debates, but they were entirely focused on the issues. Not the people behind the issue. We learnt how to disagree violently, while still showing warmth and love for the person behind the disagreement.<p>As a teenager, I thought this was the default in society. It was only after leaving home and going to college, that I realized it was the opposite. Whereas my family took disagreements as an opportunity for lively debate (and a bit of fun in the process), too many people take disagreements as an insult and a personal affront. One can only hope that this tide will swing back around the other way.
