Some lessons you learn the hard way. Years ago, I learned mine about gambling on football the hardest way. I paid cash. The ball bounces funny and not just some of the time.
Bad bounces happen.
So do injuries. So do fumbles. So does strange weather. So do deflected passes that find the wrong hands, causing a fluke touchdown that causes your team, which dominated the game, to lose in the final seconds. Stupid bets happen, too.
