Most fans I know are pretty single minded, whichever team they choose to root for. Personally, I've known several people who claim they are fans of both teams and I can't understand that. I don't see how you can have equal allegiance to both - either you're a Met fan or a Yucks fan, not both. I just don't get it. I know I couldn't do both.
There are a lot of people who are bandwagon fans, who just get behind a team when they're doing well. For me, that's taking the easy way out. I was brought up in a household of Mets fans (except my dad, he was a Yucks fan), and they taught me that you stand by your team - and your favorite players - no matter what. That's why I use my sig line, courtesy of the Boss (the REAL Boss). As far as I'm concerened, there is no retreat and no surrender...under ANY circumstances.
Like soldiers in the winter night with a vow to defend,
No retreat, and baby...NO SURRENDER!!!
