My basic mode of teamwork with many of my colleagues is surface antagonism. I have a co-worker, same team, similar title, who's therefore not actually on many of my project teams, with whom I have a constant barrage of joking insults go back and forth--it's established that my boss and manager flip between staying out of the middle and keeping us separated. He basically has first dibs on talking trash about me.
There's another guy I sling shit with, a developer who's on, like, half my projects. Yesterday morning I get an email from him and another developer, informing me about some sort of issue that makes *no* sense to me, and it takes me some exchanges to work out it's not actually one of my projects, so freakout forestalled.
The way this developer and I work is that he constantly begs to not have anything to do with me or any of my projects, and always fights back when I ask him to do anything, and my angle is that I'm entirely responsible for any success he's ever had at the company (including before I joined), and that if it weren't for me, he'd never get anything done. To outsiders, it probably looks really weird and antagonistic.
Yesterday, when I asked why I was getting those emails he said "Why aren't you on all my projects? It would make things so much simpler." I've had an intense week so far, but that was one of the most touching things I've had anyone say to me, and I'll absolutely never remind him he said that.
