To keep it brief: there is a girl who I've seen around campus for the past few semesters. I've passed up more than a few opportunities to ask her out and by the next time we can see each other, there will only be a few months before we are on different sides of the country again. I want to salvage whatever I can and was thinking about getting in touch with her this summer. Is there any point in doing this if I can't actually be with her for another 6 months? If so, what would appropriate for people who are just acquaintances? Email? Call? Text?
