My son has really been getting into the Beatles lately, which made this exchange in the car timely.
We were listening to Seventies on 7 on Sirius XM's satellite radio feed, and on came Got To Get You Into My Life.
Me: Ack - that's not the Seventies! It came out in '66!
Nick: (Calmly) Dad ... let it be. Just let it be.
Me: Good joke, Nick!
Nick: (Slight pause) Um ...
Me: That was deliberate, right?
Nick: (Another slight pause) Nooo.
But then he chuckled, and I found myself no longer in times of trouble.
