I use to work at this telemarketing place like 2 years ago. One day this random girl was sitting next to me and i didn't even read up on any techniques or anything back then. So after making basic conversations and stuff, she added me on fb after that first encounter, and I haven't seen her since then. I never spoke to her on fb or anything. So today I wished her happy bday, and she replied: Thanks you!! Long time no see though

She's pretty, I wouldn't mind meeting her and making making out and whatnot. So what do I do from here?
