Comment Lunch. (Score 1) 361
Always go to lunch with coworkers, and chat with them about... anything, or just hang out while they chat if you can join a group doing so.
If they want to talk work, ask them what they're working on; if something in what they say is actually interesting to you, ask 'em about it. If they don't want to talk work, where do they live? Where did they go to school? What do they think of both? What did they do this week? Ideally, they want to talk work at least part of the time, as that's likely more useful. :-)
At lunch, if you find yourself talking more than a fair share, work on talking less. If you find yourself talking not at all, work on talking slightly more.
