So your thinking about how to approach and make the interaction go in your favor. You're thinking of all the possible variables of what you would say and how she would respond. Will she be favorable or distant. How can you show interest without showing too much. What if she says she has a bf. EH!! Stop!......
When this happens just like an electric shock this will pop into your head.......fuck it!!
Nike. Just do it!

I agree with most of the posts above. You're thinking too hard. I go away for school for 8 months at a time. My neighbours and good friends don't think it's weird when I talk to the after coming back to my home town. They enjoy catching up with me. This girl is going to be in the same boat.
You need to relax your mind and as yourself, "what is the worst thing that can happen?"
