<human>: At my old work there are a lot of young people. I was working as a supervisor on my shifts, but all 25 employees are around the same age, so my job basically meant a bit more money and hours. A place like this leads to fun parties after work, and a lot of friends. 

I started dating a colleague, which of course spread through the workplace, I think we saw eachother for a month or so, before we decided it didn't work out. Lisa was her name. She had transfered to our divison along with 6 of her friends, I only got to meet one of them before I left for another job, the rest came in days and weeks after I left. I live with one of my colleagues from that job, and I regularly see some of them all.

Here is the hazzle. Shortly after I left, this new, astonishingly beautiful and sweet girl started, lets call her Carla. One of my ex-dates friends. I really want to date her (or atleast talk to her), I know she is single and is currently having a boring life (her own words to my roomie) so I know there is room for me to fit in her schedule too. She knows who I am, especially cause I slept with her friend over a months course, and that is a common joke still - but we haven't actually met. I don't meet Lisa anymore, but we are 'friends'. There is no way of getting her to introduce me (which is also a bit weird in our circle of friends), I can't casually add her on facebook or anything, and also, I have no clue if the chances of me getting to know her are ZERO due to me and Lisa, or if she is not bothered by it. Roomie tells me she is picky and that is why she is not seeing anyone, or haven't for a while, but that he thinks I can go for it - IF I find an appropriate way to meet her.

Any way to spontaneously meet a girl on purpose, for the sake of getting to know her, without her knowing you really want to date her?

Can you give me the gist of the text in a nutshell?
<bot>: Complicated situation with a girl, dunno how to meet her as we are not 'friends' yet. Wanna ask her out, but no way of doing so.
