If you have not read my first Instructable on the issue, then get your butt over to the first one and read it! (It will help you understand this instructable)
Step 1: Spot the Girl and Talk to Her
The first thing you need to do is to find a girl because without that all this information is useless.
Walk up to her and just say "Hello" if she says "Hello" then you may continue talking to her.
Ask her what her name is. If she tells you to go away, then she is not interested. If she tells you her name then you may continue.
Ask her a couple of questions. It really helps in getting to know her and making your self look like you really want to talk to her. Also, throw in a couple comments about your self too. For example: if she says she like ice-cream and you do too, tell her that.
Be funny!!! Girls like funny guys no matter what they look like.
Remember to act nice to her. Girls like it when you talk to them like they are a human being and not just an alien from Mars.
Also it is IMPERATIVE that you remember to be confident. Girls are attracted to confidence.
Don't be afraid to use cheesy lines so long as you say them in a sarcastic tone. That way she knows that you are just saying them to seem funny, and most girls will find it funny and you will get some laughs.
If you only take away one thing from this step let it be this: It's not what you say or how you say it, it's having the guts to say something at all.
Step 2: Get Her Number
After you talk to her for a bit and have begun to get a good vibe, ask for her number. And don't just "ask" for her number, put some feeling into it. Demand it if you want to be really confident. You can also just sneak it into a conversation. What I find works for me is asking her if she would want to talk to me some more, and if she says yes then I ask.
Step 3: To Be Continued (Again)
Keep checking back for Episode 3 of my Girlfriend series. We will be discussing how to communicate with a girl so as to not be a friend, but possibly be something more.
