Senior moments

As you age, it's all but impossible to wonder if you're starting to "lose it". For me, that "Big Sixty" birthday is just around the corner, and yes, I'm worried by my senior moments. You'll understand, of course, that I don't tell you about them. I'm old, and somewhat forgetful, but not completely frigging clueless.
I love my dad, with no qualifiers. He has many of the attibutes I'd love to have one day - strength of convictions (in fact, an unswerving conviction that he's never, ever been wrong), a prodigious talent for multi-octave gas passing, and he knows that he is the best looking man that's ever lived. So I love and respect him, but at the same time, every once in a while, I don't mind teasing him a little.
I went by his place for my normal Sunday afternoon visit the other day and after a while, he told me that he'd "made a mistake" that morning. He got up then and went into the kitchen for something, then came back and sat down. Two or three minutes passed and finally I said, "Ok, finish telling me about your mistake."
As has happened before, he briefly showed his little grin and told me that he drove to church in the rain and had trouble backing into his parking spot because it was hard to see well, but finally made it. He then grabbed his umbrella and the tote-like bag in which he carries his Bible and went inside. When he came out after church, his car was still running. He'd forgotten to turn the car off, so it sat running all the while he was inside praying, perhaps for no more senior moments.
One of my first thoughts was that it was good this happened at church, where there is a slightly higher than average number of honest folks. Then I wondered if I should advise him to not tell my sisters about it, but I can't remember now whether I did or not. Obviously we already share at least one trait, and on second thought, perhaps I am clueless.
