As much as Laker and Celtic fans don't like each other, deep down we know we're in the same boat.
We laughed, and we both kept going our way. Last year, after game 7 a Celtic fan and I were talking in Game Stop, when he finally noticed I was wearing a Laker polo shirt (for the true Prep Gangstas out there). He then matter of factly said "fuck you." Then he said sorry and that loss really made him bitter. I said I knew what it was like, we nodded, and went back to talking about whatever Bro Shooter we were talking about.
Us Laker and Celtic fans, we don't like each other, but we understand each other. We are cut from the same cloth. We're used to cheering for the teams that America claims they hate. But we don't care. We know that we were lucky enough to be born near the two most dominant franchises in basketball, and we're not going to back down from that and pretend to be Clipper fans. Since Boston is so terribly cold, we tend to be around each other a lot too, since half of Boston is living in California, Nevada and Arizona, prime Laker fan territory (make no mistake, the only people in Arizona who like the Suns live in Phoenix).
I'm horribly antisocial. I'm very shy. I find social situations to be terrifying. But if I see an obvious Celtic fan, I usually say something. Because at the very least, we have something to talk about automatically. Sometimes I'm taunting, sometimes I'm being taunted, sometimes I'm actually just saying hello. But Celtic fans are like family. A family that I want to be better than at all times.
