I think I already shared my story before, but here's again anyway: When I was ten years old, my father bought me a Bird's jersey (my first NBA jersey, no less), and he shared some stories about Larry Legend and the Celtics in general. In that moment I knew I wanted to be a fan of the best franchise in the NBA.
However, I'm from Argentina and back in those days, good luck if could catch an NBA game on TV. And when that happened, it was usually because the Bulls were playing (the most popular team by far, at the time). So it was hard to keep up feeding my fandom.
But then, a couple of years later, I got my first computer so with the help of Basketball games and the Internet I revived the love I had for the Celtics (starting during the Pitino era!) and kept growing to become what it is today: I watch all 82 games of the regular season + the postseason (if I missed one for whatever reason, I keep myself out of Twitter, sports TV and Celticsblog until I have the time to watch it); when we lose, it changes my day; when we win, it changes my week (unless there's a loss in the middle). You know, just like the rest of you.
