I was recently with a friend who was relating some of the things his parents let him do when he was a kid. He followed it with "What the hell were they thinking?"
I then responded, "Or maybe, what the hell are parents today thinking? Seems like you turned out pretty well."
Which is just a reminder for all of us. No one knew what the hell they were doing, no one knows what the hell they are doing, and no one will know what the hell they are doing.
That doesn't mean we don't keep trying but we do probably start trying to judge a little less.
