You can tell the difference between Shiites and Sunnis when you've been around them a long time, too. Socially, the Sunnis here are more openly laid-back. The Shiites who aren't fundamentalist are a little more reserved about things, but most of them don't have religious hang-ups. I have met a few who do, though. And they maintain distance with us. They're polite, but you can tell they're not friendly towards us.
