Today is my dad's birthday. He died a couple of years ago, but today I honor his memory. When I was growing up with my three brothers, we would often be sitting at the dining room table talking about the day. I, or one of my brothers, would make some wild assertion about something we had heard. My dad, who was trained as an engineer, taught us the art of "skeptical inquiry" by looking at us with a raised eyebrow and saying, "Really? Show me the facts!" We would be forced to defend what we had said - which, of course, we often couldn't do.
So on your birthday, Dad, here's to you. You taught us well.
