Any advice on getting a girl under some strange circumstances?

Hello, please forgive my long winded story. I am going to explain the how and why of my situation.





So there's this girl. I've liked her for a long time, since high school in fact. Right now I am 24 years old, and even though I figured after graduation, I wouldn't come across her anymore, in the past 6 years we've crossed paths a handful of times. But wait, there's more!





Two/three years ago I worked at a grocery store; a few months before I left, the girl's -sister- started working there. Yet despite leaving that job I still see the sister on an irregular basis, and the reason for that is she and a co-worker got into a relationship of their own; this co-worker just so happened to be a friend of my present roommate (if that didn't make sense, I apologize). In other words, I still see old co-worker and sister because they are friends with my roommate, and thus indirect friends of mine. In this sort of weird, twisted way, there is this vague and indirect connection between myself and the girl in question.





The problem is, and while I hate to admit it, is that I still think about her from time to time. I've always been a rather quiet, shy, non-social type in the past, but now I am starting to think differently. I cannot deny what I want and feel, but how to communicate with her is something I am not quite sure about. There doesn't seem to be an obvious way to simply communicate with this girl without it being weird. And by weird I mean, me popping out of the woodwork and saying ';Hey what's up! Remember me??'; It would be nice if there was some coincidental meeting out in some social setting, but the chances of that actually happening are probably astoundingly low.





What it comes down to, is that it seems weird to me to ask about her to either coworker or sister, or maybe it's just me. It also seems weird to come out of nowhere, so to speak, to just communicate (as in, by email or something, considering the chance of us crossing paths are slim), but once again maybe it's just me. Does anyone have any advice or can possibly add some perspective on this matter for me? Am I totally insane or just mostly insane? Thank you. :)Any advice on getting a girl under some strange circumstances?
Why can't you just call her? That's not so weird. Tell her you've been thinking about her and take her out for coffee or something. You guys can catch up on what you've been doing since high school. If she doesn't seem interested in the conversation, then all you've invested in the relationship is a cup of coffee so you can go on with your life. If you two get along, ask her out on more of an official date. Go do something fun with her!





P.S. I'm the shy type too so I feel your pain but I definitely think you should just call her out of the blue. If I were her, I would think that was pretty cool that someone from years ago was thinking about me. Good luck!
