But at least he didn't betray his ancestors. So if you don't want your kids to betray your team, here's what you do.
Just dress the kids in your team's gear, hat and jersey and so on, and take them to the other ballpark when the game is on during the Cubs-Sox series. Sox fans, take your kids to Wrigley. Cubs fans, take your kids to Sox Park.
Just stand outside, holding your child's hand, until a crowd of boisterous drunken fans from the other team approaches, fans shouting "Sox suck!" or "Cubs suck!"
Now here's the tricky part. Just let go of your child's hand and run away.
That's right. Run. Leave them there, alone in the teeming crowd, with the screaming, angry, drunken fans cursing the Cubs or the Sox. Yes, the kid may be terrified. But it works.
After a few minutes, return and hug your child. With some kids, you must repeat the process for several games. But once indoctrinated, they'll remain loyal.

"I'll never forget it," said the other boy. "There was a big fat Cubs fan, he was drooling all over his shirt, saying Sox suck, Sox suck! He was drunk and he smelled!"
"That traumatized us," said his brother. "The drool flopping down, the beer breath, more drool. Thanks, Dad, you're the best."
