I recently was paired with a female coworker my age for a day. I have been on friendly terms with her but I got the vibe that she was maybe interested in me. As the day went by we made small talk and were friendly although they were shallow conversations as she doesn't do anything outside of work and isn't that well read (which I wasn't that into) but regardless as time went by I realized I don't know how to flirt. I was friendly, made a bunch of jokes (none self depreciating either) and she laughed a lot but I don't know how to escalate a conversation, what to say, etc. and ended up making small talk until the shift was over. While I don't think dating a coworker is a good idea, I should know how to flirt and ask girls out by now without appearing autismo (like I usually do with everyone) as I'm in my late 20s. I don't know what her takeaway was, if she thinks I'm autistic (which I might be), just overly nice, or gay (which I'm not), but I'm not too worried about what she thinks. I'm just concerned about my lack of social skills. How do you ask a girl out? How do you flirt? What do you say?
