How do I talk to a girl that is no longer in any of my classes?

[Amalek]

The only possible time I ever get to see her is lunch....
Should I try to get into social media (twitter, instagram?)

How should I approach her?

[Connor]

The only way to talk to her without seeming weird is to stop her in the hall or talk to her in the cafeteria. Get a small conversation going and see if you can get her social media connections or cell phone number (preferably cell #), then you'll be able to go from there.

Here's a few articles that will help you prepare for that talk:
