I often feel like saying that to my dad. The problem is he's been dead for 22 years.
Another problem is, I didn't speak to him when he was alive; but then he didn't speak to me either. Kind of made us even. A nicely balanced equation; all factors balancing. Except life doesn't demand the mathematical discipline of precision. We can and do introduce into our lives discordant factors. Things don't always balance on either side of the equal sign. Yet this shouldn't stop us communicating with each other.
Today I'm riven with regret that I let my dad pass away without saying goodbye, sorry and I love you. Merry Christmas, dad, wherever you are.
