anyybody have advice for putting game at work on one of my co-workers

Too be honest, depending on how much you see this girl, you might not be able to game her, if she see's you all the time then it's difficult to be how you are when picking up ALL the time, on occassions i am sure she will see you being different, leading her to wonder about you. If your naturally a flirty guy, ( i think i am :L i get accused off trying to get a date from the chicks at work by other co-workers, so i would say i'm flirtatious) Just be yourself man, but on occasion make sexual innuendo's (so easy when you think about it) just to get her thinking about you like that. Trust me, I am not experienced but that's my opinion anyway. Throw NEG's, she should be comfortable with you already so she shouldn't be offended, DONT cross the line though.

Good luck, Make sure it doesn't get messy though man.
