Hey all,
I'd like to hear everyone's opinion on this, no matter how positive or negative, as I like to see all angles and I don't get butt hurt easy. It's a semi-long story.

Recently broken up, I'm in college and have a class with this cute girl. We aren't really acquainted with each other, but after noticing her for about a month of eye-fucking me every time I turn around, I approached and #-closed on her on a Friday noon after class was over. The approach was good, she was smiling but I sensed that it was probably due to her being a shy girl. Before leaving, I negged her about giving me a fake cell number so I called her right then and there. I have her number and she has mine.

Three days later on Monday evening, I give her a call. Rings like 6 times, goes to voice-mail and I don't leave a voice message. I expected this, no problem. On Wednesday afternoon, I sent her a text and a convo went like this:

Me: OMG all the sexy looking people are being kidnapped by aliens! You'll be safe, I'm just texting to say bye.
4 mins later
Her: WTF?? Who is this??
14 mins later
Me: I'll give you a call on Friday, Sherlock Holmes, if you haven't figured it out by then.
11 mins later
Her: Um please don't. I don't talk to creepers.

At this point, I kinda chuckled at it and stopped texting. Friday comes, I originally planned to talk to her AFTER class, but she sits closer to the exit than I do so by the time I even get up, she's already disappeared. I could've ran after her, but I didn't want to look needy. So two hours after our class was dismissed, I call her phone. As I expected, 5-6 rings and it goes to voice-mail and I leave a message like this:

Me: "Hey badass, this is ____, from your favorite class, Organic Chemistry. Call me back and we'll do some chit-chatting. Alright, bye!"

Initially, I felt real positive about this, but after a buddy of mine pointed out a couple of red-flags, it got me thinking a little. Now, I understand women have their little rules as guys do about returning calls. Still, I think perhaps I misread her signals and I was just something cute to look at while she passed time in boring chemistry class.

I don't know enough to tell you how you should have played it, but I know enough to tell you where you fucked up. The aliens thing was really weird to say because you don't know her well. If you all actually talked some before, it may have been fine. Also, the Sherlock Holmes thing came off as super creepy.

IMO, you need to know a girl a little better to be able to pull off the more complex jokes. Not sure what you should have said otherwise, so if anyone else has advice...
