Hello, I'm new to posting here, but I've learned a lot from reading everyone's great advice. After a few things happened last night, I began wondering if perhaps I've completely ignored girls who have been interested in me in the past, just because I was unprepared for (or didn't even recognize) their IOIs.

Just a little about myself. I'm an attractive and intelligent guy in my mid-20s. I generally don't have to do much to get girls interested in me, but I find it very difficult to transfer that initial interest to action. (Either I try to hard, or not at all)

Last night I was out celebrating a friend's birthday at a club and just dancing and chatting with my friends not really looking to pick up girls.

At the end of the evening, I was waiting in line to get my coat and so I chatted up the girl behind me. She was nice and talkative. After I got my coat I said good night and ran to catch up with my friends. But after I said good night, she blew me a kiss. I've been blown many kisses before, but all of a sudden I thought that this could be an IOI. But I thought I would seem desperate going back to her to chat her up after saying goodbye. What should I have done? I get these air kisses all the time and don't really know how to escalate from there...
