My wife an I have different birthdays, but we were both married on the same day. Is that a coincidence?
I was at a business conference with a coworker, and she started chatting with another attendee. They both learned they had sons that played high school football (same league, different schools). The other gentleman said his son was the starting quarterback, and lost the final game of the season to my coworker's son's school. In the final minutes of the game, the quarterback was sacked, fumbled, our team recovered and scored, winning the game and the league championship.
My coworker beamed as she said "Yes. My son sacked him."
