When a Method Can Do Nothing, Michael Feathers:

Here’s a sports metaphor: the Dallas Cowboys are a widely disliked sports team, for various reasons. If I was from anywhere but Dallas, it would be “not cool” to count myself one a fan. But being from Dallas, I have an entirely different view on the Cowboys and can safely watch their mostly mediocre performances with occasional memories of greatness, safe from scorn.

I find that holding that tension in my head is important when talking to sports fans. It’s the same with OO: you haven’t read the books, watched the presentations, or worked the exercises I have. We’re on different pages, but we need to talk about the same code and how to structure it. There’s a tension between my understanding of OO and the next person, but it’s not a barrier. We have to get our language straight before we can talk about language!

In short, we have to establish what city in OO-land we’re from before we can effectively talk about OO.
