<human>: Hi everyone. I have a date planned next week with this awesome girl I work part-time with, I'm 21 and she's 24 (I don't see her everyday), and our job requires to be physically fit. So we went running together last week and it ended up being just a walk and talk in the park. In my perspective we have a nice chemistry, no awkward silences whatsoever, we have things to talk about etc.. Then we went to grab a snack which I paid for, nothing special. Question 1: Was paying for it a mistake? 

A couple of days after, I asked her out for a date at this somewhat expensive restaurant where you eat in complete darkness (We talked about that place that day we trained together and we found out that we both are curious about it). Question 2 : It's technically our first date. And it seems like going to have dinner in a nice place is not suggested for a first date. What should I do? tell her that we should go somewhere more relax like a couple of drinks? 

Am I over-thinking stuff? She is not the greatest texter ever, she seems less friendly and/or not interested at all in me when we talk via any other method than face to face. But she agreed for a date. Am I missing something? Is it just her type of writing because the Facebook posts she makes project the same "coldness" you know what I mean? I don't understand the signals here. 

What should I do in order to have a successful first date and not kill my chances to advance further? 

Thanks for the time reading this and helping me out!

Can you provide a brief overview of the text?
