Ok, monday evening I was on my friends photo exhibition and I met a girl.
She is a friend of one of my female friends from high school, but I haven't seen her for 4 years, so this girl didn't have any previous info/impression about me.

This girl and I started talking, she was giving me lots of IOIs - she would punch me in the shoulder when I was teasing her, she put her palm on my chest, she was laughing constantly and having fun, we were taking pictures of each other, she told me stuff like "omg, you are so crazy" etc.

I also hang out with other people, than I would come back to her etc.

I made a great first impression, but what now? I added her as a friend on facebook, and she confirmed but we didn't exchange any messages.
I didn't want to act needy. I also have her cell phone number.

Should I call her, or text her? Arrange some typical low-risk meeting like coffe, or something more interesting like going to the ZOO.

I was thinking of something like: "We had fun the other evening, but I don't know anything about you, we should meet up"

I don't want to mess this up, so I could really use some good advice.

Anyone?

well i'd say phone her mang, cuase if u spend to much time texting and that kind of lingo, ur attraction will wear off, am i right boys? try get together fast as possible, maybe u could phone her from a payphone and go" come to the mall with me and my friends" than when she gets there u can say ur friends left to see a movie, than moe power to u, well do what u fell like, i'm no expert lol
