Hi mate,
if you opened her, there is not really a point in having topics if she doesnt have much time. So, the first thing you should do is figure out if she is willing to talk right now (someplace where you can sit and perhaps drink something). If not, go for a rendez-vous at another time.
Anyways, the original topic was about topics when you actually get to a conversation. Well mate, that is actually not as hard as you might think. In that short period of time, you should be trying to get to know her as thoroughly as you can. So you would want to ask questions about stuff that you want to know. And dont take stupid oneliners for an answer. Expect more, expect her to open up to you, so that you can open up to her so that she eventually might open up her legs again to you
.
Example of a bad question: 'where do you come from' - answer: 'Germany', 'Lalaland', 'Middle-Earth'. This is a bad question because it can be answered with one word. While it is a question about her and probably also about something you want to know, this is a shallow question. If she is a real interesting person, then it matters where she lives but in the beginning, you dont know yet if she is interesting.
example of a good question: 'How come you had an awful day?' - answer: 'Just because'. the question is a good one, but her answer is a bit... fuzzy. you really want to know how her day was and what could be the cause of her feeling awful about the day. So could reply with: 'but why?'. here she might look at you as if to see if you are really interested in knowing. So look back at her like you are expecting a full detail explanation. When she did her explanation, relate to it. To close my post, i ll give an example of how a conversation might go.
you: "so, how was your day" (bad question, but, you gotta start somewhere!
her: "Awful"
you: "Awful? Really? how come you had an awful day?
her:"oh, just because"
you:"nah, i wont accept 'just because'. Tell me why. Unless you are manic depressed or suicidal... you arent suicidal are you?"
her (with a faint smile):"hehe, no no, i am not"
you:"thank god! now tell me why your day was awful".
her: "well, its just my job! today i got yelled at for the most stupid things that werent even my fault!"
you: "ooh i know that feeling! It feels so... incorrect. If i was in your situation, i would be angry and swear bloody revenge!"
her: (grinning) hehe yeah indeed! But i am not angry actually, but at the time, i felt so insecure.
you: (relate to feeling insecure in this situation or relate by telling her a likewise story that happened to you once. just be honest in your stories. dont brag, just tell her how you would feel or how you felt. women smell bullshit from miles away
).
hope it helped!
good luck!
