<human>: Give me a shortened version of the text

Hey guys!

I'm 19, female, and new to the dating scene. I'm starting my sophomore year of college and I got out of my first relationship towards the end of my freshman year. That relationship started in high school so I haven't done too much actual dating. 

I met my date (22, female) on OkCupid. We're seeing each other tomorrow (today, technically as it's past 12AM where I am) and are getting coffee.

I know I'm over thinking things but I hope you guys will humor me. This girl seems really sweet and I'd like to make a good first impression. 

I'm REALLY unsure about the whole "who pays" dance, especially since we met online and we're both girls (not to say guys always have to pay but my brother says he always does and no girl bats an eye). She suggested the meeting, but I contacted her first. Are there "rules" about this? 

There's also a large chance that I'll get off work early tomorrow and, if so, I'll probs just head over to the coffeehouse early (it would be like 15 minutes or so, I work really close). In that case, would it be weird if I texted her something like "Hey I got here a few minutes early to grab a table, what's your drink order?". That way, I could just pay and stop stressing.

Also, I purposely tried to keep my messages kind of short so we'd have stuff to talk about. Any tips for good conversation topics? I'm not socially awkward but I do get nervous. 

One reason I think I'm kind of freaked out is that this girl is a bit older than me and her profile specifically said she didn't want anyone younger than 21. I was pretty surprised she responded to me. I think I'm psyching myself out about this. 3 years isn't a huge difference but she graduated from college this summer and has a real job. Has anyone out of college dated someone still in undergrad? Is there any advice you'd give to me?

Really, if anyone has any other good first date tips I'd really appreciate them.
<bot>: Going on a first date with a girl who is a bit older than me. I need advice on how not to be nervous and how to handle who pays. Should get there early and just text her for her drink order?
