This FR is quite long and detailed. It's a different sarge as it happened at work. Tho there's not much action in it, I think it may be interesting anyway. HB is a girl at work, and I feel stupid for not being able to read her signals, so here we go..
The background
HB works at a staffing company, so she's being sent as a consultant to different companies for short periods of time (often only a few days). So, I've been working with her every now and then, and fluffing with her a bit, however not really flirting, since I was an AFC at the time and didn't know how to. However, I haven't seen her for a long time, until yesterday, when she came back for a two-days assignment.
The kind of work that I do (for 5 more weeks, then "so long suckers, I'm off" - oh yeah) is typical factory work. There's a conveyor belt, there are machines to run and maintain and there are pallets to move around. Yesterday was the kind of day when I'd be all over the place, doing a little bit of this over here, then a little bit of that over there, talking to everyone and making sure to have a good time while doing it. So when I met her in the midst of all this, I think my interactions with everyone was somewhat a DHV. Also, speaking to her for a while, taking off and then coming back every now and then for another brief conversation is probably a good thing too. So gaming came pretty natural in this setting.
Building attraction
However, I started doing some C&F stuff, like borrowing a pallet puller from her, looking into her eyes in a flirtatious way saying "I'll give it back if you're a good girl" and stuff like that, but then just mixing it up with neutral conversation. However, I didn't really know how to initiate a deeper conversation with her in order to build comfort without looking like I was trying too hard (there was no natural way to just stop by where she was and strike up a conversation). Until this:
I saw her standing working with whatever, and a few steps further away was this guy I haven't talked to for a while, so I started a loud conversation (officially it was loud in order to cover the distance between us and the noise from the machines, but the real reason was that I wanted her to hear it) about how I have handed in my letter of resignation and will finish my studies. My idea was to give her something to start a conversation with later on, but she ended up approaching and taking part in the discussion right there on the spot, which was obviously good as well.
A bit later I saw her in the cafeteria. My work mates were waiting for me by one table, and she was alone reading the paper by another table. I felt social pressure to sit with my work mates, so I missed that opportunity, but when she stood up to get back to work, I exchanged a few words with her. She went off and then came back to ask me to let her back in as she didn't have an access card. I followed her to the door, opened it and told her that I was about to leave for the day soon (however, I was planning to go back to the factory floor before leaving, so I was in no rush to close, but she didn't know this). Well, this was probably our last time working together, and she seemed to be thinking about that when she said "well, I'll see you, take care", hesitated and then went back in. It felt like an IOI the way she said it, but I have no actual way of knowing that.
Working on the close
Now, I was in a wonderful spot this particular day, because my work group had been assigned some work that's really none of our responsibility, and we said "OK, we'll do it, on the condition that we can go home after we're finished and still get payed for a full 12 hours of work". Yeah, we got 12 hour shifts. Our boss agreed on our terms and we finished after 5 hours.
So at this point, I was already off work, but I stayed just to chat with some work mates and with her.
OK, so I went back to the factory floor, just to talk to some of my work mates before leaving and to meet her up one last time. I slowly worked my way through the floor, talking to everyone I met, until I reached the position where she'd been working. She wasn't there. Having been discrete about my intentions with her, I didn't want to ask anyone about her whereabouts, but I really thought she'd headed home and I'd lost her. However, a few minutes later I found her at another place plastic-wrapping pallets.
She was doing this with a male consultant from the same staffing company, whom I've been talking to quite a bit. I stuck around there talking to both of them, and every now and then sticking something slightly flirtatios in towards her, still being very discrete tho. The male consultant said that he had also handed in his letter of resignation, so this may be the last time we worked together. I told him to give me his Facebook name, which he did. When he went off with a newly wrapped pallet, I turned to HB saying "I should take yours to", handing her a pen and a paper.
HB: I don't use Facebook
Me: OK, then just write your number, cause you and I are gonna go out for a beer.
HB: I don't drink beer
Me: Yeah, they usually have drinks as well
HB: It really sounds as if I'm dissing you saying 'I don't use facebook and I don't drink beer', but you can take my number
Then she wrote her number, I took the note back and turned to talk to someone who passed by, just in order to not make a big deal out of it. I think this last conversation is the thing I'm having the most problems interpreting. Was she going out of her way telling me that she was NOT dissing me, or was she dissing me but then giving me her number as a pity favor?
We talked casually after that, and pretty soon she finished her work and was off for the day. "I'll hear from you soon", she said and headed off.
Trying for a day 2 the same day
Coming home about 2 hours later, I realized that she said she lived in a house only about 200 meters from mine. I texted her, and we talked about our evening plans - we where both planning to just hit the slack. So I invited her over "since we're doing the same thing 200 meters from each other, we could do it together instead", to which she responded "I'd love to do that some other day, but tonight I just feel like staying at home".
Does that mean that she actually would love to do that some other day, is she dissing me, or is it neutral?
Now what?
Also, tonight I'm going to a party. She's working and probably getting off work pretty soon, so should I casually invite her to the party or should I just let things cool off for a while? It's probably not a good thing to be rejected two days in a row, but aside from that, tonight is probably a better chance than any one that I might get for a few weeks, because it's Friday and I got a party to go to. My schedule is too tight for the most part..
Also, if that's relevant in any way, she doesn't drink.
As usual, any comments are much appreciated, both quick ones and late responses. Thank you beforehand!
