Cheers Don. I actually intended to edit my post but since you agree I'll leave it alone :)
What made me think about changing it was the fact that I have many instances in my memory where I've been mean to someone and then regretted it. Whether here, among friends when a kid or just losing patience with my own kids now and then.
There are quite a few moments in my life I'd like to revisit and do things differently.
They all have one thing in common though. They are all times when I was unpleasant, never when I was nice.
