Thanks for the feedback. It's all really helpful. Yeah I realized last night afterwards that I failed to build attraction. I've always been the "Nice Guy" so that's going to take some work. Also, I didn't mention, but earlier than night, she walked past me and we made eye contact, so I think she already had some attraction to me.
Anyway, I sent her a text a few hours afterwards.
Me: Hey Blah, this is Matt, and here's my number. Save it, because it's the most important one you will ever get.

(Ok, maybe not...but save it anyway.

) *This was a brilliant text opener I found on this site. So I can't take credit for it, haha.*
Her: Haha hey! And of course i have to save it. its the death penalty if i dont :0
Me: Haha. no, you'd just have to sit through more silent auctions. Anyway, how'd the rest of the auction go?
Her: Thats worse than death lol. And I guess well. It went fast after you left because stuff started picking up and actually going.
Me: Oh well. It sounds like I missed the party. Anyway, I'm about to get some sleep. My roommate wants me to wake up early and workout before church, smh. Goodnight. *We briefly talked about church so I figure it was safe*
Anyway, I haven't talked since then and I don't plan on texting today or tomorrow. I'll probably send her something on Tuesday Night (2 days) and ask if she wants to go bowling on Thursday.
