Given your situation, I'd say it's a "hey, I know you" smile. It means little, other than her acknoledging you in a situation where she sees you regularly. I wouldn't get worked up over it. You don't have to feel pressured to start a conversation with her, although feel free to do so. Just because she has a boyfriend doesn't mean she can't enjoy talking to other guys. If you feel comfortable enough, go ahead and talk to her. Ask her about where she works, and go from there. The society nowadays is cold and impersonal, especially for aspies. So if that girl is nice enough to acknowledge you, why not talk to her and make her commute more interesting?
H-m-m.
I'm not sure that wouldn't be going further than she intends. I'll stand by my advice to just smile back. You might even throw in a "Hi," but anything beyond that might be inappropriate.
