Not really a cold approach more warm, I was going to my local library to study but it was closed. A guy was already there pissed off because it was supposed to be open and another girl walked to the door as well. I asked the girl if there were any other places were computers were on campus, she gave me some locations and I headed that way. She then interrupted as I was walking away to tell me more things. Lightbulb in head moment. So I then started walking with her and chatting, when it was time to go separate ways I asked if she was down to get a drink. She said yes pretty excitedly. I really don't think I would have picked up on the subtle cues she was giving me a year ago. And to be honest I don't think I would've had the balls if she was hot. Anyways I got the number after a long time of not approaching. I might start cold approaching again soon.
