you gotta be realistic bro..
whoever said pass her a note is a fucking kid..
1st: Where do you see her at? in the neighborhood, school, work?
2nd: Start a conversation about some you KNOW you have in common.
Neighborhood: If she lives in the same apt building as you, say some thing like "Is your water working cuz mine isnt" or some bull shit like that to start a convo, and then go from there
School: "Hey what did you get for answer # 5?"
Work: Just ask her something that relates to job and yours..
BE careful at work cause you can fired for doing some stupid shit like harrassment.. just ask josh.
3rd: By this this time you should know if she is really interested in you or if she was just being polite. If it seems like she aint interested, that just start swingin for the fences.. ask her to go out somewhere.. what the worst that could happen? get rejected? big deal.. try another girl the next day.
If she does seem interested then continue to crank it up a notch and ask her about her personal life a lil bit. And if she really likes you every thing will be easy from there yo.....
