It's just baseball so who really cares anyhow? I mean, if it were something significant like hockey and you liked the Bruins, well, you'd obviously be beyond redemption, but if you were say a Devils fan and moved to LA, liking the Kings would be fine.
... er, ... um ... okay.
If you have found Your Team For Life, you are entitled, nay required, to cheer for YTFL always. You must be very careful in selecting YTFL, as you can have only one (per sport, I guess.) Do not mistake a significant infatuation with Your Team, and think that you have found YTFL ... you must be careful, and remember that a tatoo may well be involved ... and the odds of some other team (a) having the exact same name and (b) becoming YTFL are pretty slim ... unless of course you are a CFL afficionado and like the Roughriders. (Canadian joke.)
Of course, part of your son's growing up process is finding His Own Team For Life. As part of the growing up process he may want to cheer with you, or cheer against you, but none of that is really selecting HOTFL (although that may eventually lead to the selection of HOTFL.) You can encourage him in the proper direction, but ultimately it is his decision and you must accept it. Of course, if HOTFL is different from YTFL, you are both allowed (and encouraged) to razz each other mercilessly (within the proper bounds of guy-hood) over the comparative success of the two teams. (Yes, one day soon he will rhyme "sox" with "sux" and remind you of that repeatedly. Children love repetition.)
But seriously ... baseball??
Be there or be square. Only I can do both!
I've got a cat named Beefeater and a dog named Beefeater, and two goldfish called Beefeater and Beefeater. There's Beefeater my hamster and Beefeater my horse, and my piglet, known as Beefeater of course.
