There's this really attractive girl in my school. She's a grade below me so I don't have any classes with her, plus I only see her once or twice in school. How do I approach her without making it really awkward and creepy? And what should I say to her? I have no idea what to do so far. Thanks!

Well next time you see her try to catch her eye and smile. Now she knows you are there and that you might like her. Next time you see her do the same again, check out what her response is. Did she smile back? if she did next time you see her try saying Hi! Don't rush anything, it takes time. Just make sure she notices you and check out her reaction then think of more things you can say to her whenever you see her.

Bluerose is right catch her eye and smile, and see her reaction, if she smiles say hi, and get to know her by name, and see if you click. Don't rush you have to see if she is relaxed and comfortable with you.
